摘要：【原文】The invention provides a biomass-based hyperbranched adsorption material with multi-adsorption sites to multiple heavy metal ions and a preparation method thereof. The biomass-based hyperbranched adsorption material with multi-adsorption sites to multiple heavy metal ions is prepared by one-step instant-crosslinking method using a biomass raw material as matrix and a hyperbranched polymer containing chelating atoms of N, O, and S as functional reagent, wherein the hyperbranched polymer has two or more different adsorption sites (containing elements such as N, S, O, etc.) to heavy metal ions.
本发明提供了一种基于生物质的多元吸附位点对多种重金属离子的超支化吸附材料及其制备方法。这种基于生物质的多元吸附位点对多种重金属离子超支化吸附材料是通过一步瞬时交联法制成的，该法使用生物质原料作为基体，以及含有N、O和S的螯合原子的超支化聚合物作为功能试剂。其中，超支化聚合物具有两个或多个不同的对重金属离子的吸附位点（包含元素如N、S、O等）。
