Abstract: Silica gel modified with pyridinium ion, Si(CH2)3{A figure is presented}C5H5Cl- was used to adsorb metal ions from acetone and ethanol solutions. Adsorption of anionic complexes MCln z-n (M = Co(II) and Cu(II)) was much higher from acetone than from ethanol solution. For Co(II) the adsorbed species was the tetrahedral CoCl4 2- complexes from both solvents while for Cu(II), the adsorbed species was CuCl4 2- from ethanol solution and the dimeric Cu2Cl6 2- from acetone solution. © 1990.
