Abstract
Poly acrylic acid (PAA) was used to fixed heavy metal ions. Some effects to fixed abilities of polymer with heavy metal ions such as fixed time, pH, polymer concentrations, temperatures were studied. The results show that optimal conditions for the fixed heavy metal ions: time reaction 50 minutes; molecular weight 5.106(đv.C); pH 6; 0.04% polymer concentration. In addition, properties of polyme fixed heavy metals were characterized by FTIR.Keywords: Poly acrylic acid, sorption heavy metals, fixed heavy metal ions
