A Comparison Study Of Cu(II) Adsorption Between TDI-LFG and 4TDI-LFG Polymers

AbstractIn this study, a 4TDI-LFG polymer was used to remove Cu(II) ions from aqueous solutions. The TDI amount of previously synthesized polymer (TDI-LFG) was changed and the 4TDI-LFG polymer was prepared. The effect of pH, stirring time, polymer dose and initial metal concentration on the Cu(II) adsorption by 4TDI-LFG have been investigated with batch adsorption experiments. The influence of different TDI amounts in the polymer content were evaluated
