Abstract
In recent years, interest in green solvents, which are environmentally friendly, easy to prepare and biodegradable, and in their applications in chemistry has considerably increased. In the current study, a new and easy deep eutectic solvent-based liquid-phase microextraction method compatible with green chemistry principles was developed for preconcentration of Pb (II) ions. The amount of Pb (II) ions was determined with graphite furnace atomic absorption spectrometry (GFAAS). Various analytical parameters such as deep eutectic solvent (DES) ratio and amount, ligand amount, pH, sample volume were optimized and the effects of potential matrix ions on the method were investigated. The preconcentration factor of the method was found to be 160, while the limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.071 µg L-1 and 0.236 µg L-1, respectively. The developed procedure was performed to determine Pb (II) ions in lake and river waters, and the accuracy of the procedure was determined with certified reference wastewater (SPS-WW1) analysis.

Abstract
AbstractTwo extraction procedures, namely dispersive liquid-liquid microextraction (DLLME) and dispersive liquid-liquid microextraction based on solidification of floating organic drop (DLLME-SFOD), have been compared for the spectrophotometric determination of Fe (III). In both procedures, Fe (III) was extracted after complexation with gallic acid in the presence of cetyltrimethylammonium bromide (CTAB). Tetrachloroethylene and 1-undecanol were used as extraction solvents in DLLME and DLLME-SFOD, respectively, while acetone was used as dispersing solvents. The effects of various experimental parameters (solution pH, the concentration of ligand and CTAB, as well as nature and amount of extraction and disperser solvents) on the extraction efficiency were investigated. Under optimum conditions, the calibration graphs were linear in the range of 50.0–650.0 and 8.0–800.0 μg L−1 and the detection limits were 15.0 and 5.0 μg L−1 for DLLME and DLLME-SFOD, respectively. The presence of NaCl, up to 1.0% (w/v) did not impact the extraction procedures. The analyte was good tolerated in the presence of most concomitant ions. The procedures were applied for the determination of Fe (III) in standard reference materials and real samples with good recoveries (95.5–99.0%) for DLLME-SFOD while poor recoveries (68.0–82.5%) were obtained when DLLME was applied. The analytical figures of the procedures were comparable with those listed in the literature and it could be concluded that DLLME-SFOD may be considered one of the best tools used for preconcentration of Fe (III), owing to its simplicity, time-saving and the possibility of using in conventional analytical laboratories.

Abstract
Heavy metal microextraction and determination in daily used water is accurately achieved by applying nano-clay as an extractor. The conditions for adsorption/elution of Cu(ii), Cd(ii) and Pb(ii) were investigated by adjusting the pH of samples, sample volume and the type of eluent. The nano-clay showed superior efficiency for microextraction of Cu(ii), Cd(ii) and Pb(ii) at pH 2 using 2 mL of nitric acid (1 M) as the eluent. The microextraction procedure showed high recovery% by changing the sample volume from 15 mL to 70 mL. The preconcentration factor was found to be 37.5. The LOD and LOQ were 1.8, 1.3, and 1.9 μg L-1 and 5.3, 3.9, and 5.7 μg L-1 for Cu(ii), Cd(ii) and Pb(ii) respectively. The addition/recovery from different water samples showed recovery% in the range 88-105 which confirms the efficiency and the accuracy of the developed solid phase microextraction using nano-clay for enrichment of Cu(ii), Cd(ii) and Pb(ii).

Abstract
Background::
Cadmium (Cd2+) is considered to be one of the most important hazardous
heavy metals due to its toxicity for living organisms at low concentration levels. Therefore, the
estimation of trace Cd2+ in different types of various samples is a very important objective for
chemists using effective methods. In the present work, a novel, green, easy and fast ultrasoundassisted
ionic liquid-dispersive liquid phase microextraction technique (UA-IL-DLPME) was
developed to preconcentrate and determine trace quantities of cadmium (Cd2+) ions from real
samples, prior to detection by FAAS.
Methods:
The proposed technique is based on utilization of ionic liquid (IL) (1-hexyl-3-
methylimidazolium tris(pentafluoroethyl)trifluorophosphate [HMIM][FAP]) as an extraction solvent
for Cd2+ ions after complexation with 2-(6-methylbenzothiazolylazo)-6-nitrophenol (MBTANP) at
pH 7.0. The impact of different analytical parameters on the microextraction efficiency was
investigated. The validation of the proposed procedure was verified by the test of two certified
reference materials (TMDA-51.3 fortified water, SRM spinach leaves 1570A) applying the standard
addition method.
Results:
In the range of 2.0-200 μg L−1, the calibration graph was linear. Limit of detection,
preconcentration factor and the relative standard deviation (RSD %, 100 μg L-1, n=5) as precision
was 0.1 μg L-1, 100 and 3.1%, respectively.
Conclusion:
Green UA-IL-DLPME method was developed and applied to preconcentrate and determine
trace quantities of Cd2+ in real water, vegetables and hair samples with satisfactory results.

Abstract
Microextraction procedures for the separation of Pb(II) from water and food samples extracts were developed. A deep eutectic solvent composed of α-benzoin oxime and iron(III) chloride dissolved in phenol was applied as a phase separator support. In addition, this deep eutectic mixture worked as an efficient extractor of Pb(II). The developed microextraction process showed a high ability to tolerate the common coexisting ions in the real samples. The optimum conditions for quantitative recoveries of Pb(II) from aqueous extracts were at pH 2.0, conducted by adding 150 µL from the deep eutectic solvent. The quantitative recoveries were obtained with various initial sample volumes up to 30 mL. Limits of detection and limits of quantification of 0.008 and 0.025 µg L-1 were achieved with a relative standard deviation (RSD%) of 2.9, which indicates the accuracy and sensitivity of the developed procedure. Recoveries from the reference materials, including TMDA 64.2, TMDA 53.3, and NCSDC-73349, were 100%, 97%, and 102%, respectively. Real samples, such as tap, lake, and river water, as well as food samples, including salted peanuts, chickpeas, roasted yellow corn, pistachios, and almonds, were successfully applied for Pb(II) analysis by atomic absorption spectroscopy (AAS) after applying the developed deep eutectic solvent-based microextraction procedures.

Abstract
Background:
Cadmium (Cd2+) and lead (Pb2+) have acute and chronic effects on humans
and other living organisms. In the present work, new, green and accurate dispersive micro solid-phase
extraction (DμSPE) method for the separation and preconcentration of trace amounts of cadmium
(Cd2+) and lead (Pb2+) ions in various food, water and tobacco samples collected from Saudi Arabia
prior to its Flame Atomic Absorption Spectrometric (FAAS) determinations was developed.
Methods:
The proposed method was based on a combination of oxidized multiwalled carbon
nanotubes (O-MWCNTs) with a new chelating agent 5-benzyl-4-[4-methoxybenzylideneamino)-4H-
1,2,4-triazole-3-thiol (BMBATT) to enrich and separate trace levels of Cd2+ and Pb2+. The effect of
separation parameters was investigated. The validation of the proposed preconcentration procedure
was performed using certified reference materials.
Results:
Analyte recovery values ranged from 95-102%, indicating that the method is highly accurate.
Furthermore, precision was demonstrated by the relative standard deviation (RSD < 3.0%). The limits
of detection were 0.08 and 0.1 μg L−1 for Cd2+ and Pb2+ ions, respectively. The preconcentration factor
was 200.
Conclusion:
The proposed method was used for the estimation of Cd2+ and Pb2+ ion content in various
real samples, and satisfactory results were obtained. The proposed method has high adsorption
capacity, rapid adsorption equilibrium, extremely low LODs, high preconcentration factors and
shortens the time of sample preparation in comparison to classical SPE.

Abstract
A novel method was developed for determination of trace amounts of lead in water and food samples. Solidified floating organic drop microextraction was used to preconcentrate the lead ion. After the analyte was complexed with 1-(2-pyridylazo)-2-naphthol, undecanol and acetonitrile were added as extraction and dispersive solvent, respectively. Variables such as pH, volumes of extraction and dispersive solvents, and concentration of chelating agent were optimized. Under the optimum conditions, the detection limit of Pb (II) was determined as 0.042 µg L-1 with an enrichment factor of 300. The relative standard deviation is <10%. Accuracy of the developed procedure was evaluated by the analysis of certified reference material of human hair (NCS DC 73347) and wastewater (SPS-WW2) with satisfactory results. The developed procedure was then successfully applied to biscuit and water samples for detection of Pb (II) ions.
