酸化镍硅交联膨润土的制备及吸附性能研究

Preparation and Properties of Bentonite Cross-Linked by Sillicon and Aluminum

摘要: 用酸化镍硅交联膨润土处理模拟含磷、酚废水.实验表明:吸附剂用量为8 g/L,pH=8~9,吸附时间15~20 min为吸附的最佳条件,在此条件下苯酚的去除率为87%,磷的去除率达到98.0%.与未酸化镍硅交联膨润土相比酸化交联土对苯酚的去除率提高了4%,磷的去除率提高了11%.

Abstract: The Acid-activated and Ni-Si cross-linked bentonite is synthesized and used to adsorb phosphorus or phenol in imitated wastewater.The optimum adsorption was achieved at conditions of pH=8～9,the amount of adsorbent 8g/L and stirring time 15～20 min.The phosphorus was removed by 98% and phenol by 87%.Compared with non-acid-activated and Ni-Si cross-linked bentonite,the removal ratio of phosphorus was improved by 11% and that of phenol by 4%.
