PRECONCENTRATION OF Cd2+ IN DIFFERENT SAMPLES BY CHEMICALLY MODIFIED SIO2-DHAQ NANOPARTICLES
A new analytical method using 1,8-dihydroxyanthraquinone modified SiO2 nanoparticles as solid-phase extractant has been developed for the preconcentration of trace amounts of Cd2+ in different samples. Conditions of the analysis such as preconcentration factor, effect of pH, sample volume, shaking t...
