A novel adsorbent, superparamagnetic nano iron oxide loaded poly (acrylamide-co-acrylic acid) hydrogel (superparamagnetic PAA hydrogel), was employed for the removal of toxic lead ions from aqueous solution. The influence of pH, contact time, metal ion concentration, adsorbent dose and temperature on the sensitivity of the removal process was investigated. The synthesized copolymer was magnetized insitu and the size, structure and coating of magnetic nano particles were characterized by TEM,

This hydrogel has been found to be an efficient adsorbent for toxic Pb 2+ ions removal from water (>98% removal) and could be regenerated efficiently (>99%).
