The adsorbents were obtained by modifying the natural N-N'-bis (3- triethoxysilylpropyl) thiocarbamide aluminosilicates with BTM-3 and an aqueous solution of HCl. The physicochemical properties of the obtained samples and their natural analogues were investigated. Isotherms of adsorption of nickel (II) and copper (II) ions are built.
