Heterogeneous catalytic degradation of polyacrylamide solution

Abstract

Degradation of polyacrylamide (PAM) in aqueous solution was studied by using Fe₂O₃/Al₂O₃ as heterogeneous catalyst in the presence of H₂O₂. Effects of catalyst preparation conditions such as impregnated materials and adding different trace metal elements to catalyst activity were studied, respectively. It was observed that compared with FeSO₄, the Fe(III) catalyst prepared with Fe(NO₃)₃ as the impregnated material showed better catalyst activity. Modified with trace metal elements, the catalytic activity of Fe₂O₃/Al₂O₃ could be changed greatly. Among various trace metal elements, Fe₂O₃/Al₂O₃ catalysts modified with Co and Cu showed great increase on catalytic activity.
