外文摘要：Over the past ten years research at the University of Montana in collaboration withPurity Systems Inc， both located in Missoula， Montana， has resulted in a novel class ofchelator materials composed of amorphous， nanoporous silica gels and modified polyamines。These materials offer some distinct advantages over conventional polystyrene based resinsespecially for applications in the mining industry。 This paper will report on the relationshipbetween polymer structure and metal selectivity， the relationship between chelator structureand metal selectivity and further comparisons with polystyrene analogs。
