腐植酸与糠醛废渣复合制备Cu^(2+)络合剂的研究

Study on the Compound of Humic Acid a waste residue Furfural for Chelating Precipitate Cu2^(2+)ion

本文应用正交实验法,对腐植酸与糠醛产生中的废渣生成的复合物对废水溶液中Cu2+进行了系统的络合沉淀研究, 发现腐植酸与废渣提取物复合后所得的复合物,对重金属Cu2+有较好的络合沉淀作用,而且形成的沉淀物含水量较低,有利 于分离。进一步的研究有望成为具有实用价值的Cu2+离子络合剂。

This paper studied on the chelating precipitate agent of Cu2+ion by means of the compound of Hu—mic acid a waste residue of furfural,through the orthogonal experiment.It was found that the compoundhaving better chelating precipitate effect than a single Humic acid,and precipitation having little water thanprecipitation used a single Humic acid.Hence the compound of Humic acid waste residue of furfural is likelyto be used chelating precipitate Cu2+in waste water.
