Combined cation-exchange and extraction chromatographic method of pre-concentration and concomitant separation of Cu(II) with high molecular mass liquid cation exchanger after its online detection

Detection and selective sample clean-up of beryllium(ii) through {extractor-HOMO}(:){Be3O(OH)2}2+ ‘ion pair complexation’ amidst aluminum(iii) and uranium(vi) by employing a fluorescent resin: the resin's HOMO amount is a quantitative descriptor of BTC

Under optimum sorption conditions, FSG–PAN forms 1 : 1 ‘ion pairs’ with {Be₃O(OH)₂}²⁺, {Al₃(OH)₃(H₂O)₂}⁶⁺ and {(UO₂)₂(OH)₂(H₂O)₇}²⁺.

n-Capric acid-anchored silanized silica gel: its application to sample clean-up of Th(iv) sorbed as a dinuclear species in quantified H-bonded dimeric metal-trapping cores

nCA anchored to SSG surface generates 121 μM g⁻¹ H-bonded metal-trapping cores with 10-fold increase in surface area for selective uptake of {Th₂(OH)₂(H₂O)₂}⁶⁺.

In vivo detection of fluoride at trace levels and its removal from raw water at neutral pH utilizing a cyanobacterium pigment as a luminescent probe

A selective method has been developed for trace level (0.01 mg L⁻¹) fluoride detection in HEPES buffer in the presence of interfering ions (such as Cl⁻, I⁻, Br⁻, SO₄²⁻, ClO₄⁻, and CH₃COO⁻) using a cyanobacterium as a luminescent probe.

EBT anchored SiO2 3-D microarray: a simultaneous entrapper of two different metal centers at high and low oxidation states using its highest occupied and lowest unoccupied molecular orbital, respectively
