Studies On Tin (IV) - Based Ion-Exchangers
Abstract
The antimonate (V), tungstate (VI), molybdate (VI), and arsenate (III) of tin (IV) have been synthesized. Sorption of nickel and magnesium on these sample has been studied at pH 4.0 as a function of nickel ion and magnesium ion concentration. The sorption of nickel was found to decrease in the order molybdate (VI), antimonate (V), tungstate (VI), and arsenate (III). The trend of adsorption of magnesium was similar to that of nickel. The distribution coefficients of nickel and magnesium on the four samples for various initial cation concentrations established the selectivity Ni > Mg. Repeated treatment of the samples with 1.0 M NaC1 and 1.0 M HNO3 solutions tended to decrease the capacities to certain minimum values.
