粉末活性炭对邻苯二甲酸二乙酯的吸附性能研究

考察了投加粉末活性炭吸附去除水中邻苯二甲酸二乙酯的可行性，并采用Freundlich公式拟合纯水和原水条件下的等温吸附方程。试验结果表明，采用粉末活性炭可有效去除水中邻苯二甲酸二乙酯，活性炭投加量为30mg／L，吸附120min后，纯水和原水条件下邻苯二甲酸二乙酯去除率分别为93．3％和89．3％。根据吸附等温方程计算得出，以邻苯二甲酸二乙酯的标准限值（0．3mg／L）为平衡浓度，纯水、原水条件下最大投炭量（80mg／L）可应对的邻苯二甲酸二乙酯最高质量浓度分别为7．575和5．731mg／L。

Adsorption of diethyl phthalate by powdered activated carbon

The feasibility of diethyl phthalate removal from the water by powdered activated carbon(PAC) was investigated,the Freundlich formula was adopted to simulate the isothermal adsorption equation under the condition of pure water or raw water.The experimental results showed that PAC could effectively remove diethyl phthalate from the water,and the removal rates of diethyl phthalate in pure water or raw water were 93.3% and 89.3% respectively when PAC dosage was 30 mg/L with an adsorption time of 120 min.Accord...
