摘要
以钠基膨润土为基本原料,通过酸活化和焙烧活化两种改性方法,制备了酸化膨润土和焙烧膨润土,并研究了膨润土原材料及改性膨润土净化材料对空气中甲醛的净化效果。结果表明,酸化膨润土和焙烧膨润土比原钠基膨润土对空气中甲醛的净化效果有较大幅度的提高,净化率分别为77%,80%和69%。因此,膨润土是一种新型理想的空气净化材料。
The two kinds of modified Na-bentonite( acid bentonite and calcined bentonite) were prepared using Na-bentonite as raw material. The purification effect of formaldehyde in air of the Na-bentonite and modified Na-bentonite was studied. The results show the purification effect of the modified Na-bentonite are improved greatly than the original Na-bentonite, and the removal efficiency is 77%, 80% and 69% respectively. The Na-bentonite is a new kind of ideal air purification materials.
