【摘要】 分别采用溴代十六烷基吡啶(CPB)与十六烷基三甲基溴化铵(HDTMA)改性的天然沸石处理含Cr(Ⅵ)废水。对其性能与影响因素进行了比较,实验结果表明:CPB改性沸石的性能优于HDTMA改性沸石。CPB改性沸石的最佳改性浓度为1 0%,最佳改性温度为30℃,吸附时间为20min,吸附容量为HDTMA改性沸石的4倍。更多还原

【Abstract】 The natural zeolite, modified by CPB and HDTMA separately, is used to treat Cr(Ⅵ)-containing wastewater and its (influencing) (factors) are studied. The experimental result shows: the performance of CPB modified zeolite is superior to HDTMA modified (zeolite). CPB modified zeolite’s optimal modified density is 1.0%, optimal modified temperature is 30℃, adsorption time is 20min,and adsorbing capacity is 4 times than that of HDTMA modified zeolite.更多还原
