Problem
The present invention provides, in a metal-adsorbing material used for the removal and recovery of a wide range of heavy metals in treated solutions such as industrial waste water, service water, and environmental water, a gel-like metal-adsorbing material having a large amount of metal adsorption and capable of meeting various demands; and also provide a metal adsorbent having a gel-like metal-adsorbing material supported on a porous carrier.
Means for Resolution
A metal-adsorbing polymer selected from polyethyleneimine and polyallylamine is crosslinked with a polyglycidyl ether, whereby a gel-like metal-adsorbing material having a large amount of metal adsorption and capable of meeting various demands is produced. Further, a hydrophilic porous carrier is impregnated with a metal-adsorbing polymer, followed by crosslinking with a polyglycidyl ether, whereby a metal adsorbent having a gel-like metal-adsorbing material supported on the porous carrier, which has a large amount of metal adsorption and can meet various demands, is produced.
问题
本发明提供了一种用于去除和回收工业废水、服务用水和环境用水等处理溶液中多种重金属的金属吸附材料,该材料为凝胶状金属吸附材料,具有较大的金属吸附量,能够满足各种需求;同时还提供了一种金属吸附剂,该金属吸附剂具有支撑在多孔载体上的凝胶状金属吸附材料。
解决方法
将选自聚乙烯亚胺和聚烯丙基胺的金属吸附聚合物与聚缩水甘油醚交联,从而制备出具有大量金属吸附性并能满足各种需求的凝胶状金属吸附材料。进一步,在亲水性多孔载体上浸渍金属吸附聚合物,然后与聚缩水甘油醚交联,从而制得具有凝胶状金属吸附材料的金属吸附剂,该金属吸附剂支撑在多孔载体上,具有大量金属吸附性,可满足各种需求。
