- Montmorillonite (MMT) Na-modificated by suspensoid was modified using cetyltrimethyl ammonium bromide (CTAB) and dodecyltrimethyl ammonium chloride (DTAC), and CTAB-modified montmorillonite (CTAB-MMT) and DTAC-modified montmorillonite (DTAC-MMT) were obtained at the optimum conditions: the reaction temperature 60 , the reaction time 1h, the pH 5 and the reaction temperature 50 , the reaction time 1h and the pH 9, respectively. It was confirmed by infrared spectrometer that the quaternary ammonium salts(QAC) had been successfully intercalated into montmorillonite. The activity of removal algae in landscape water for CTAB-MMT and DTAC-MMT were investigated comparatively with MMT, respectively. The results showed that removal rates of CTAB-MMT for Diatom and Cyanobacteria were 20.75% and 22.89% higher than that of MMT, and similarly these of DTAC-MMT were 25.85% and 24.99%.
