腐植酸与纤维素的复合物对废水中重金属离子络合性能的研究
Study on the Chelating Heavy Metal Ion in Wastewater by Means of Compound of the Humic Acid and Cellulose
【摘要】 风化煤中提取的腐植酸类物质对废水中有害重金属离子具有一定的络合作用 ,但有沉积速度慢、时间长、沉积物不易分离等缺点 .本文用腐植酸钠与纤维素反应产生的复合物 ,对水中重金属离子的络合性能进行了研究 ,发现络合效果比单纯用腐植酸钠效果要好 .因而腐植酸纤维素复合物有望成为重金属污水处理剂 .
【Abstract】 The humic acid substances extracted from the efflorescence coal have some chetating function to the poisonous heavy metal ions in wastewater. However, they have such shortcomings as slow rate and long period of precipitates as well as difficulty in separating the precipitates. This parer studies the synthetic features of the chelating capacity of heary metal ion in wactewater by means of the reaction between humic acid and cellulose. The experiment shows better chelating effect than the original method. Hence the compound of humic acid and cellulose is likely to be used in wastewater treatment.
