| 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 rain. 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%. |

| Keywords: | bentonite Ni-Si cross-linked modification adsorption water treatment |
