Abstract
We have synthesized silica-based sorbents with an MSM-48 pore structure, modified with hydrazide and amide groups based on Versatic tret-carboxylic acids, and investigated their textural and structural properties. The kinetics of Cu(II), Ni(II), and Co(II) sorption on the sorbents from aqueous solutions have been studied, and the effects of the silica modification process and modifier concentration on the sorption capacity of the silicas for the three metals present together have been examined. The synthesized sorbents have been shown to be capable of separating the nonferrous metals studied.
