摘　　要：采用硫酸铝对膨润土进行改性制得除臭剂，并对除臭剂吸臭性能进行了研究，通过Ｘ射线衍射分析，研究了改性膨润土除臭机理。试验表明，硫酸铝溶液中，聚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，该聚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。From experimental study,a kind of deodorentswere ma de by aluminum sulfate modifying bentonite.By means of absorptiontests and X-ra y diffraction analysis,the absorption properties anddeodorizing mechanism were studied in detail.It seems that in aluminumsulfate solution,the polyions of alu minum enter the space between thelayers of montmorillonite crystal and enlarge the space afterhydrolysis.when the modified bentonite absorbent is used to trea t smellywater,the polyions vacate the space into the water and function as coagulant.With the result,more smelly organisms are absorbed in the enlargedspace. 
