analytical, optical, and thermal study of sulphonated polystyrene prepared from some industrial polystyrene waste

In this study sulfonated polystyrene (sps) was prepared from some industrial waste polystyrene (ps). the degree of sulfonated and molecular weight were determined. an analytical study was evaluated for sps to determine the efficiency of chelating some ions (zn, cu, and pb). the binding capacity of the sulfonated ps toward metal ions was studied in different ph (2.5, 4.5, and 6.5) under continuous shaking for affixed time of 6 hours at laboratory temperature. optical properties studied for this polymer and energy gap values culcalet of the polymer. finally, some thermal parameter was calculated from the tga thermogram to evaluate thermal stability of these polymers.
