文摘A new type of bead crosslinked chelating resins containing coordinate atoms N and S were synthesized by the reaction of polyethyleneimine with chlorometbylthiirane in suitable sovent at temperature of 2080C. These chelating resins exhibited excellent adsorption properties for precious metal ions.
