%X In this study, a series of inorganic-organic composite polymer was prepared. Magnesium hydroxide and polyacrylamide was composed in a composite matrix to prepare Mg(OH)2-PAM (MHPAM) inorganic-organic composite polymer. The characteristics of MHPAM inorganic-organic composite polymer was investigated in terms of chemical, physical, physical, thermal and morphological properties through FT-IR, conductivity, intrinsic viscosity, TGA and TEM, respectively. Results showed that the properties of MHPAM composite polymers varied with the compositions in the composite polymers. Different compositions of MHPAM inorganic-organic composite polymers were applied in removing reactive dye from aqueous solution. MHPAM inorganic-organic composite polymer with Mg(OH)2 : PAM ratio of 90 : 10 gave the best dye removal (%) where it was able to remove 98% of reactive dye at pH 11.00 with a dosage of 500 mg/L. Kinetics study was carried out using different dye concentration and it was found that the experimental data fitted the pseudo-second-order model better compared to pseudo-first-order model.
