Synthesis and Application of PAFSi

The research is focused on the production of different molar ratio complex wastewater coagulants from bentonite by a series of ways,such as acid,alkali,oxidation,and polymerization.The factors which affected the extraction efficiency of silicon oxides from bentonite were the concentration of NaOH,reaction temperature and time.The optimum conditions as proportion,dosage,sedimentation time,and pH were determined.These samples exhibit a significantly better coagulation performance in treating living wastewater under the applied experimental conditions.
