Synthesis and Application of Novel Heavy Metal Ions Chelator
Polyacrylamide-urea-sulfanilamide(PUS) was prepared as a novel heavy metal ions chelator and successfully used to simultaneously remove heavy metals from wastewater effluents. The effects of reaction parameters (sodium hydroxide, material ratio, temperature and contact time) were monitored to specify the best synthesis conditions. PUS was chemically characterized by means of infrared spectroscopy (FTIR). The simultaneous chelation performance of PUS towards selected heavy metals ions, nickel, copper, lead, cadmium and zinc, was discussed, and Ni2+, Cu2+, Pb2+, Zn2+ can be chelated better especially, indicating that the synthesized PUS is a potential remediation material when used for the treatment of wastewater containing metal ions.
