A Preconcentration Procedure Using 1-(2-Pyridylazo)-2-napthol Anchored to Silica Nanoparticle for the Analysis of Cadmium in Different Samples
A new analytical method using 1-(2-pyridylazo)-2-naphthol modified SiO2 nanoparticles as solid-phase extractant has been developed for the preconcentration of trace amounts of Cd(II) in different water samples. Conditions of the analysis such as preconcentration factor, effect of pH, sample volume,...
