摘要
研究了高比表面氮化硼（BN）对水体中氯苯的吸附规律。采用静态吸附法研究发现氮化硼对氯苯的吸附过程符合一级动力学模型和Freundlich等温吸附模型。研究结果表明,pH值为6-7,吸附时间为2h时,氮化硼对氯苯的去除率达到了79%,吸附饱和量可达到672.8mg/g。
The adsorption performance of boron nitride with a high specific surface area on chlorobenzene in the water was investigated. The results got from the static state adsorption experiments are fitted very well with those gotten from the pseudo-first-order kinetic model and the Freundlich model. It indicated the removal rate of chlorobenzene reaches about 79% after adsorption 2 h at pH 6-7, and the adsorption capacity can reach as high as 672.8 mg/g.
