膨润土是一种优良的吸附剂,但是其本身对油的吸附效果较差。本研究以聚丙烯酰胺和四甲基溴化铵作为改性剂,对钠基膨润土进行改性。结果表明,当改性膨润土用量为7.5g/L时,对含油废水的吸附效果可达85.7%。
The removal of oil from water is highly desired due to frequent oil spill accidents,as well as the increase of industrial oily wastewater.So we hope to develop an adsorbent for oily wastewater.Bentonite is an excellent adsorbent,but its adsorption on oil is poor.Polyacrylamide and tetramethyl ammonium bromide were employed to modify Na-bentonite.The results shown that when the amount of modified bentonite was 7.5g/L,the adsorption effect on oily wastewater can reach 85.7%.
