Removal of Cu(II), Pb(II) and Fe(III) ions from aqueous solutions was studied by using a new adsorbent synthesised by hydrolysis and subsequent condensation of Ti(OPrII)(4) by sol-gel process. Metal ion adsorption was highly increased when the adsorbent surface was covered with a coating solution of hydrolysed NH2- and SH-functional silanes prepared in methanol. Adsorption conditions for Cu, Pb and Fe ions were optimized. It was concluded that Cu was retained to 100% on SH-functional silane coated adsorbents, whereas Fe(III) and Pb(II), 89% and 100%, resp., on NH2-functional silane coated adsorbents.
