Abstract

Removing the hazardous metals from wastewater especially industrial drainage is very important for preventing health problems in human beings, plants and animals. The ion exchanger has constructed as primary line of safeguards for that goal. In this study grafted polyamide-6 (PA-6) fibers with polymethacrylic acid (PMAA) was used as materials for the ion exchangers. Grafting was achieved under required time and temperature and the factors affecting the graft process were studied. The efficiency of the grafted fibers for adsorption of Cu2+, Pb2+ and Cr6+ was evaluated. The effect of adsorption parameters such as pH, duration of adsorption, initial ion concentration and the adsorption temperature on the degree of extraction (R %) and adsorption capacity (SC, mg/g) was studied. Optimization the conditions for the preparation on laboratory scale, adjustment and adaptation of these conditions to suit the production of these grafted fibers on pilot scale was accomplished.
