Aluminium chloride enhanced polyacrylamide AlCl3-PAM hybrid polymcr has been synthesized in this study. Aluminium chloride was synthesized with polyacrylamide via free radical solution polymerization to fabricate inorganic-organic hybrid polymer AlCl3-PAM. A redox initiation system - NH42S2O8 and NaHSO3 was used to initiate the polymerization at 50;C in aqueous medium. Fourier Transform Infrared Spectrometer FT-IR Was used to characterize aluminium chloride-polyacrylamide hybrid polymer by determining its functional groups exist in the hybrid polymer chain. Inorganic aluminium chloride salt was incorporated into the polyacrylamide to enhance the aggregation ability at kaolin particle interface. A physico-chemical method which is flocculation was used in this study to flocculate kaolin suspension. The effect of pH on the flocculation of kaolin suspension was studied between pH 5 to 7.5. The result showed the aluminium chloride-polyacrylamide AlCl3-PAM hybrid polymer was able to remove 99 of turbidity at pH 6.5 using 5 mg/L of dosage.

Abstract

Aluminium chloride enhanced polyacrylamide AlCl3-PAM hybrid polymcr has been synthesized in this study. Aluminium chloride was synthesized with polyacrylamide via free radical solution polymerization to fabricate inorganic-organic hybrid polymer AlCl3-PAM.

Fourier Transform Infrared Spectrometer FT-IR Was used to characterize aluminium chloride-polyacrylamide hybrid polymer by determining its functional groups exist in the hybrid polymer chain. Inorganic aluminium chloride salt was incorporated into the polyacrylamide to enhance the aggregation ability at kaolin particle interface. A physico-chemical method which is flocculation was used in this study to flocculate kaolin suspension. The effect of pH on the flocculation of kaolin suspension was studied between pH 5 to 7.5. The result showed the aluminium chloride-polyacrylamide AlCl3-PAM hybrid polymer was able to remove 99 of turbidity at pH 6.5 using 5 mg/L of dosage.
