TL;DR: A new method for separation/preconcentration of trace amounts of Cr, Cu and Pb in environmental samples by magnetic solid-phase extraction (SPE) with Bismuthiol-II-immobilized magnetic nanoparticles and their determination by ICP-OES has been developed.

TL;DR: A new chromium(III)-imprinted 3-(2-aminoethylamino) propyltrimethoxysilane (AAPTS)-functionalized silica gel sorbent was synthesized by a surface imprinting technique and was employed as a selective solid-phase extraction material for speciation analysis of chromium in environmental water samples prior to its determination by inductively coupled plasma mass spectrometry (ICP-MS).

TL;DR: A simple and sensitive method using microcolumn packed with black stone for the separation/preconcentration of Cd, Co, Ni and Pb in biological samples prior to their online determination by inductively coupled plasma optical emission spectrometry (ICP-OES) has been developed.

TL;DR: In this paper, a microcolumn packed with nanometer-sized zirconia as solid phase extractor for the separation/preconcentration of Mn, Cu, Cr, Zn, Ni and Co prior to their determination by inductively coupled plasma optical emission spectrometer was proposed.

TL;DR: In this article, a simple and sensitive method has been developed using microcolumns packed with immobilized used green tea leaves (UGTLs) for the speciation of Cr(III) and Cr(VI) prior to their determination by inductively coupled plasma optical emission spectrometry (ICP-OES).
