摘要: A process for removing ions of dissolved heavy metals and complex comprises providing a treatment zone in which is contained an extraction material having activated surface that has affinity metal ions. The the reaction product polyamine with covalently anchored trifunctional hydrocarbylsilyl yields non-crosslinked amino groups to functional chelator can be attached. formed by first hydrating then silanizing hydrated short chain silane hydrocarbon substituent containing 1-6 carbon atoms terminal leaving group, reacting from silanization so as form aminohydrocarbyl polymer bound surface.
