偕胺肟螯合纤维的合成及对矿液中金的吸附性能研究

An amidoximated fiber was synthesized via a simple pathway.Its chemical and mechanical properties were determined.The static and dynamic adsorption properties to extract Au from ore liquid were studied.The highest adsorption capacities of static and dynamic were 585 mg/g and 2962 mg/g,respectively.It was concluded that this fiber might be used as a good material to extract Au from ore liquid.
