季铵盐改性蒙脱土对景观水硅藻和蓝藻的去除OACSTPCD
Removal of diatoms and cyanobacteria in landscape water by modified montmorillonite with quaternary ammonium salt
以十六烷基三甲基溴化铵(CTAB)季铵盐为表面活性剂制备改性蒙脱土,并用FT-IR进行表征分析,考察其对景观水体中不同藻类的去除作用.结果表明CTAB季铵盐已插入蒙脱土的层间,其改性蒙脱土去除硅藻的最优条件组合是:质量浓度30 mg/L,温度25℃,pH=6,时间36 h;改性蒙脱土去除蓝藻的最优条件组合是:质量浓度40 mg/L,温度35℃,pH=7,时间24 h.最优条件下CTAB季铵盐改性蒙脱土在对硅藻的去除率比未改性原土提高了20.73％…查看全部>>
The modified montmorillonite is prepared by taking CTAB quaternary ammonium salt as surfactant,and its characterization is analyzed by FT-IR.The removal of different algae in landscape water was studied.The results show that CTAB quaternary ammonium salt is successfully intercalated into the interlayer of montmorillonite.The optimum conditions for CTAB-modified montmorillonite to remove diatoms are as follows:Concentration is 30 mg/L,temperature 25 ℃,pH=6,ti…查看全部>>
