Abstract
Manganese (II) silicate has been synthesized as a gel product by direct precipitation reaction. Modifying its structure by doping with iron, cerium, vanadium and tungsten elements has been carried out. These materials were characterized using X-ray, IR ,TGA-DTA and chemical stability was studied. The prepared materials show increasing in the capacities values from 2.65, 2.55, 2.22, 1.73 and 1.50 to 3.61, 3.42, 3.11, 2.68 and 2.16 (meqg-1) for Co2+, Cd2+, Cu 2+, Cs+ and Al3+, Respectively as a result of the modification by doping. pH titration data reveal monofunctional behavior. The distribution coefficients values of metal ions have been determined at different pHs. Column application was also studied.
