Abstract
⺠Mono-amino-functional groups were found better than di- and tri-amino for Cd(II) adsorption. ⺠Amino-functional group would serve as a basic adsorption site for heavy metal ions. ⺠Mercapto- and carboxyl-groups were found to behave as ion exchange sites for proton. ⺠Introduction of amino- and mercapto-groups onto silica was proven by XPS and FT-IR measurements.
