[ 1 ] - Preconcentration and Determination of Lead for Trace Levels in Water and Wastewater Samples by Vortex-Assisted Microextraction Using TPAS as a New Synthetic Complexing Agent with Electrothermal Atomic Absorption Spectroscopy Detection
A simple and rapid solidified vortex assisted 1-undecanol based liquid-liquid microextraction technique was proposed for preconcentration of trace levels of lead ions. The extraction solvent (1-undecanol) was dispersed into the aqueous samples by the assistance of vortex agitator. 100 µL of 1-undecanol containing ethyl (2Z)-3-[(5-chloro-7-methyl[1,3]thiazolo[5,4-d]pyrimidi...
[ 2 ] - Application of Ion - Imprinted Polymer Synthesized as New Sorbent for Preconcentration and Separation of Thallium (I) and Its Determination by Electrothermal Atomic Absorption Spectroscopy
At this study, thallium (I) ion-imprinted polymer, as a novel sorbent for Tl (I) and comparison with Tl(III) ion-imprinted polymer has been synthesized. This sorbent for preconcentration and solid-phase extraction of Tl(I) ions from aqueous solutions, used. Through preparing the binary complex of Tl(I) ions with 5, 7-dichloroquinoline-8-ol (DCQ) the particles of thallium (I) Ion-Imprinted P...
