| Abstract: | Polyaluminium silicate sulfate(PASS) has been synthesized using bentonite as the raw material.The composition and process parameters for the synthesis of PASS have been optimized.It is found that Si/Al molar ratio of 1,polymerization pH of 4,polymerization temperature of 60 ℃,reaction time of 1 h and aging time of 24 h give better coagulating efficiency for simulated wastewater treatment.PASS synthesized under optimum condition shows the largest percentages of decoloration and deturbidity were as high as 83.3% and 57.1% respectively. |
