摘要
通过酸活化、焙烧活化2种方法分别对钠基和钙基膨润土进行改性,研究了不同种类膨润土对空气中甲醛的净化效果。结果表明,经酸活化改性和焙烧改性的膨润土对空气中甲醛的净化效果有大幅的提高。因此,膨润土可以作为一种新型绿色空气净化材料。
The two kinds of modified bentonite (acid bentonite and calcined bentonite) were used to modify Na-bentonite and Ca-bentonite. The purification effect of formaldehyde in air of different type of bentonite was studied. The results show that the purification effect of the acid modified and calcined modified bentonite was improved greatly than the original bentonite. Therefore, the bentonite can be used as a new kind of green air purification materials.
