【摘要】：鄰苯二甲酸酯類(PAEs)是廣泛存在于環(huán)境中的激素類化合物,以3種PAEs作為研究對象,分析不同活性炭類型對激素類物質(zhì)的吸附特性、最佳吸附量及其再生使用情況。結(jié)果表明,活性炭吸附PAEs時宜控制p H值為4~8的中性偏酸條件;PAEs去除率隨著PAEs分子質(zhì)量的增加而降低;果殼炭的吸附能力最強,對鄰苯二甲酸二甲酯(DMP)的最大吸附容量為398 mg/mg AC,其次是椰殼炭、原煤破碎炭、山西小顆�；钚蕴�、8#-Ⅱ型大顆�；钚蕴�;采用稀鹽酸+甲醇+超聲波的方式可達到一定的脫附再生效果,且延長了使用周期。
[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，
