Preparation, Characterization and Application of Mg(OH)2-PAM Inorganic-Organic Composite Polymer in Removing Reactive Dye

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
