| 摘 要： | 研究了粉末活性炭对2,4-滴、呋喃丹、甲萘威和莠去津的吸附过程和吸附规律以及投炭量和水质对粉末活性炭吸附性能的影响。结果表明,粉末活性炭能有效去除4种农药;吸附规律符合Freundlich吸附等温线和Langmuir吸附等温线;吸附时间为30 min时,去离子水中的去除率已达到80%以上;随着投炭量的增加,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可能不同,因此在应急处理中,首先应该确定该水质下的吸附等温线,然后求出投炭量。

| Abstract: | The adsorption process and adsorption law of 2,4-D, carbofuran, carbaryl and atrazine by PAC and the effect of PAC dosage and water quality on adsorption capacity of PAC were studied. The results showed that the four pesticides could be adsorbed effectively by PAC. The adsorption law obeyed both Freundlich adsorption isotherm and Langmuir adsorption isotherm. In deionized water, the removal rate got to above 80% when adsorption time was 30 min. The removal rate rose and the adsorption capacity of PAC dropped with the increase of PAC dosage. The adsorption isotherm of PAC could be different in different water qualities. Therefore, in the emergency treatment, the adsorption isotherm in the corresponding water should be determined first and then PAC dosage is calculated. |
