The interaction of Zn(II), Cd(II), and Pb(II) with 1,10-phenanthroline noncovalently immobilized on silica in the presence of Bromophenol Blue was studied. The optimum conditions of the reaction and the composition of mixed-ligand complexes that are formed at the surface were found, and a scheme was proposed for the interaction at the interface. A sorption–spectrophotometric procedure and a test scale were developed for the determination of zinc with detection limits of 0.011 and 0.018 mg/L, respectively. The procedure was used for the determination of labile zinc species in soil. [ABSTRACT FROM AUTHOR] |
