摘要
黄河中段水中3种环境类激素浓度较高。在实验室条件下采用重蒸水和黄河水分别配制邻苯二甲酸二丁酯、壬基酚和双酚A水溶液进行了活性炭吸附处理试验,结果表明活性炭对水溶液中3种物质均有较好的吸附效果,其达到吸附平衡的时间分别约为50min,30min,20min;活性炭对3种物质的吸附等温线符合Langmuir类型,吸附量分别为148.5mg/g、277.5mg/g和230.8mg/g。但在采用黄河供水中外加3种污染物的试验条件下,活性炭对邻苯二甲酸二丁酯的饱和吸附量降低,对其他两种污染物的吸附影响不大,表明水体中含有其他能够影响邻苯二甲酸二丁酯和活性炭之间吸附作用的化合物。
There is higher content of di-n-butyl phthalate, nonyl phenol and bisphenol A in the water of midstream of Yellow Rever. Laboratory jar test of activated carbon adsorption has been carried on by prepared water solution samples of pure water and Yellow River water which contained di-n-butyl phthalate, nonyl phenol and bisphenol A separately. The result showed that activated carbon had good adsorption for these 3 compounds. In case of pure water sample, adsorption equilibrium time of 50 min, 30 min, and 20 min were gotten. Further analyses showed that the adsorption isotherms of activated carbon for these 3 compounds in the pure water solutions correspond to the Langmuir type, and the saturated adsorbance was 148.5 mg/g, 277.5 mg/g,and 230.8 mg/ g. But for Yellow River water solutions, the saturated adsorbance of activated carbon to di-n-butyl phthalate reduced obviously, while for other two compounds it seemed same as the pure water solutions. This result showed that some matter may be presence, which can affect the adsorption of di-n-butyl phthalate with activated carbon.
