Selective and sensitive spectrophotometric method for the determination of trace amounts of zirconium in environmental and biological samples using 4-chloro-N-(2,6-dimethylphenyl)-2-hydroxy-5-sulfamoylbenzamide

Determination of zirconium in water, dental materials and artificial saliva after surfactant assisted dispersive ionic liquid based microextraction

A green, simple, low cost extraction method was developed for the spectrophotometric determination of Zr. The proposed method was applied to water, artificial saliva and dental materials.

Determination of trace elements in soil, leaves and fruits of Quercus brantii grown in southwestern Iran by atomic spectroscopy

Quercus brantii acorn is rich of some useful mineral elements such as K, Fe and Zn. The content of these mineral elements in Quercus are dependent on their region and environmental conditions. Q. brantii grown naturally in different regions of Iran especially in Kohgiloye va Boyer Ahmad province (southwestern of Iran). In this study total concentration of Fe, Zn and K elements were determined using atomic absorption and emission spectroscopy in fruits, leaves of Q. brantii and also in the soils where this plant was grown. Statistical evaluation (ANOVA test) was employed for all measurements. Results confirmed that the concentration of elements in fruit and leave depended on area which the plant is growth. The transport factor of elements was also considered.
