摘要
研究以阳离子表面活性剂HDTMA改性天然斜发沸石,制得HDTMA改性沸石,进而研究HDTMA改性沸石对废水中Cr(Ⅵ)的吸附特征。结果表明:HDTMA改性沸石对Cr(Ⅵ)吸附符合Langmuir等温式和拟二级动力学方程,饱和吸附量为10.99mg/g,吸附主要为化学吸附,但温度、pH值和干扰离子对HDTMA沸石吸附Cr(Ⅵ)具有明显影响。
Investigating the adsorption characteristics of HDTMA-modified-zeolite to Cr(VI) in the wastewater treatment, making the HDTMA-modified-zeolite by the cationic surfactant HDTMA-Modified Clinoptilolite. The result shows that the reaction corresponds to Langmuir isotherm and secondary dynamic reaction, the saturated adsorption is 10.99rag/g, the reaction is owing to chemical adsorption, and the factors(temperature ,pH and some anions) have great impact on it.
