突发氯苯污染的粉末活性炭吸附应急处理
Study on emergency treatment of powdered activated carbon absorption of sudden pollution of chlorobenzene
摘要
Abstract
Based on the establishment of method of determining chlorobenzene in water by liquid micro - extraction associated with gas chromatography and analysis on the adsorption kinetics and isotherms of chllorobenzene were conducted in water with 2 types of PAC. The optimal mathematical models were selected through the models used to fit the experiment data. At the same time, the effect of pH, temperature, ionic strengih, on chlorobenzne adsorption on PAC was studied. The results showed that the rate of adsorption of chlorobenzene on PAC in water was so rapid that can satisfy the water quality sandard in 15 min. The adsorption isotherm can be fitted well with Freundlich model. PAC had a large adsorption capacity of chlorobenzene when the pH value of water was closed to the isoelectric point of itself or the ionic strength was high enough in water. The adsorption of chlorobenzene on PAC was an thermic process. Temperature was conducive to PAC adsorption of chlorobenzene; high ionic strength when the PAC adsorption of large amount of chlorobenzene.关键词
