  • 摘要: 实验研究了活性炭纤维对水中敌草隆、阿特拉津的吸附行为，考察了温度、酸碱度、流速对这两种除草剂的吸附影响，采用碱液进行了活性炭纤维的再生。实验结果表明，在实验条件下，温度越高，吸附量越大，敌草隆最佳吸附pH范围在弱酸性区间，阿特拉津最佳吸附pH范围在中性区间。在动态吸附中，流速增大，吸附效果越来越差。采用浓度较小的碱液处理，活性炭纤维再生效果明显。
    Abstract: Adsorption of diuron and atrazine onto activated carbon fibers was carried out in this study,the effects of temperature,pH values and flow rate on the adsorption were investigated,respectively.The regeneration of activated carbon fibers was completed using diluted alkaline liquor.The results showed that the absorption capacity increased with the increasing temperature under the experimental conditions,the optimum adsorption interval of diuron and atrazine were in the acidic range and neutral range,respectively.In the dynamic adsorption experiment,the adsorbing effect was getting worse and worse with the increasing flow rate.Regeneration effect of activated carbon fibers was obvious when using lower concentrations of alkaline liquor treatment.
