糠醛席夫碱除去水中的重金属离子

Salicylaldehyde Schiff Base to Remove the Heavy Metals Ions in Water

由于重金属只能转化迁移不能降解的性质,废水中重金属的去除一直困扰着人们。近年来,研究较多的为利用金属捕集剂来处理含重金属离子废水。本文首先合成了糠醛双席夫碱N,N’-双(2-呋喃甲醛亚胺基乙基)-2,6-吡啶二甲酰胺(IIa),利用其与金属反应生成具有较高稳定性且不溶于水的螯合物的性质,进行了模拟废水中重金属离子的去除实验。

Due to heavy metals can not move into the degradation of nature,the removal of heavy metals in wastewater troubled people.In recent years,the use of metal trap to deal with waste water containing heavy metals was got more researches.Taking fractional steps and synthesized linear multidentate Schiff base ligand [N,N-bis（2-furfural-iminoethyl）-2,6-pyridinedicarboxylic diamide（IIa）] firstly,on the basis of their predecessors,the use of its metal and the reaction of a higher stability of the chelates not dissolved in water to the nature,and a mock heavy metal ions in wastewater removal experiment was conduct.
