| 摘 要： | 试验研究了粉末活性炭对氯丁二烯的去除效果以及吸附时间、投加量和水质对粉末活性炭吸附性能的影响。结果表明,粉末活性炭对氯丁二烯的去除率在90%以上,吸附规律符合Langmuir吸附等温线和Freunlich吸附等温线;最佳吸附时间为120min;随着投炭量的增加,氯丁二烯的去除率提高,粉末活性炭的吸附容量降低;在不同水质条件下,粉末活性炭的吸附等温线不同,因此在应急处理中,首先应确定原水水质下的吸附等温线,然后计算出投炭量。 |
| 关 键 词： | 氯丁二烯 粉末活性炭 吸附性能 吸附等温线 吸附容量 |

| Abstract: | The removal efficiency of chlorobutadiene by powdered activated carbon (PAC),the adsorption time,dosage of PAC and water quality on adsorption capacity of PAC were investigated.The results showed that the removal rate of chlorobutadiene by PAC was above 90%.The regularity of adsorption was accorded with Langmuir and Freundrich adsorption isotherm,and the optimal adsorption time was 120 min.The removal rate of chlorobutadiene was improved and the adsorption capacity of PAC was increased with increment of PAC... |
| Keywords: | chlorobutadiene PAC adsorption performance adsorption isotherm adsorption capacity |
