5种改性硅酸盐吸附剂对腐殖酸的吸附性比较
Comparative Study on Humic Acid Adsorption Capability of Five Modified Silicate Absorbents
摘要
Abstract
This paper analyzes raw and modified silicate absorbents' absorbing capability for humic acid by doing experiments with zeolite, expanded vermiculite, porcelain ceramists, shale ceramists and clay ceramists. The effects of solution pH, the dosage of modified absorbents, temperature and initial humic acid concentration on adsorption capacity of humic acid were observed. The experimental results showed that there are significant differences between zeolite and other absorbents, and the adsorbing capacity in the order were zeolite, expanded vermiculite, clay ceramists, porcelain ceramists and shale ceramists before modification. Through research, the best modifying methods and condition of five absorbents could be drawn: 20 g/L HDTMA-modified zeolite, expanded vermiculite and clay ceramists; 25 g/L HDTMA-modified shale ceramists and porcelain ceramists.关键词
