The application of organo nanoclay 1-(2-pyridylazo)-2-naphthol (PAN)-immobilized as a new, easily prepared, and stable solid sorbent for preconcentration of trace amounts of Cu2+, Ni2+, and Mn2+ ions in aqueous solution is presented. The organo nanoclay was prepared by adding tetradecyldimethylbenzylammonium

A cloud point extraction (CPE) method for the preconcentration of ultra-trace chromium speciation in human serum samples prior to determination by graphite furnace atomic absorption spectrometry (GFAAS) had been developed in this paper. In this method, Cr(III) reacts with 1-(2-pyridylazo)-2-naphthol
