A new synthetic gel was obtained by bulk polymerization of castor oil, acrylic acid and acrylamide. This paper describes the ability of this gel to uptake heavy metals and nitrate ions from aqueous solutions as demonstrated in our laboratory. Determinations, before and after batch experiments, were carried out using atomic absorption and UV spectroscopy These results showed that Al+3, Fe+3 and Pb+2 ions were effectively adsorbed.
