摘要
采用硫酸铝对膨润土进行改性制得除臭剂，详细研究了改性膨润土除臭机理。试验表明，在硫酸铝溶液中，铝离子和水合铝离子进入膨润土蒙脱石层间，并撑大了层间距，当改性膨润土投入臭水中时，铝离子和水合铝离子进入水中形成混凝剂，并空出了更大的层间，导致大量生臭有机物的吸附。
The deodorant can be prepared from modification of bentonite with Al2(SO4)3. The deodorization mechanism of the modified bentonite is investigated. The test shows the gaps between the layers of montmorillonite were enlarged with ions of aluminum and its hydrate entering into the space between the layers in Al2(SO4)3 solution. When the modified bentonite was thrown into odorous aqua, the above ion formed coagulant by going into the aqua and produced larger space between the layers and resulted in strong adsorption for odorous organisms.
