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.eninfo:eu-repo/semantics/closedAccessadsorbentadsorptionsol-gel processCuPbFeArticle12151552-s2.0-0037269022N/AWOS:000180962800008Q4
