摘要
花生壳是一种可作为吸附剂的自然资源,成本低,在染料废水治理中有很高的实用价值.本文对花生壳进行碱和酸改性处理,研究在特定条件下,未改性、酸改性、碱改性花生壳对亚甲基蓝溶液的最佳吸附条件,以及不同条件对同一类花生壳吸附效果的影响.最终实验结果表明:碱改性花生壳对亚甲基蓝的吸附性能最好,且在投加量为 0.7g、pH值为11、初始浓度为 50mg/L、吸附时间为 30min时去除率最佳为 98.31%.
Abstract
Peanut shell is a kind of natural resource which can be used as adsorbent with low cost and high practical value in the treatment of dye wastewater.In this paper,peanut shells were modified with alkali and acid,and the optimum adsorption conditions of unmodified,acid-modified and alkali-modified peanut shells for methylene blue solution under specific conditions were studied,as well as the influence of different conditions on the adsorption effect of the same kind of peanut shells.The final experimental results showed that the alkali-modified peanut shell had the best adsorption performance for methylene blue,and the best removal rate was 98.31%when the dosage was 0.7g,pH value was 11,the initial concentration was 50mg/L and the adsorption time was 30min.
