【摘要】：邻苯二甲酸酯类(PAEs)是广泛存在于环境中的激素类化合物,以3种PAEs作为研究对象,分析不同活性炭类型对激素类物质的吸附特性、最佳吸附量及其再生使用情况。结果表明,活性炭吸附PAEs时宜控制p H值为4~8的中性偏酸条件;PAEs去除率随着PAEs分子质量的增加而降低;果壳炭的吸附能力最强,对邻苯二甲酸二甲酯(DMP)的最大吸附容量为398 mg/mg AC,其次是椰壳炭、原煤破碎炭、山西小颗粒活性炭、8#-Ⅱ型大颗粒活性炭;采用稀盐酸+甲醇+超声波的方式可达到一定的脱附再生效果,且延长了使用周期。
[Abstract]:Phthalic acid ester (Pas) is a kind of hormone compounds widely existing in the environment. Three kinds of PAEs were used as the research object to analyze the adsorption characteristics, optimal adsorption capacity and regeneration usage of different activated carbon types for hormone compounds. The results showed that the removal rate of PAEs decreased with the increase of PAEs molecular weight, and the adsorption ability of char was the strongest. The maximum adsorption capacity of DMP for dimethyl phthalate was 398 mg/mg AC, followed by coconut shell charcoal, raw coal broken charcoal, Shanxi small granular activated carbon, #- 鈪，
