| Abstract | A series of superabsorbent composite, polyacrylamide/attapulgite, from acrylamide (AM) and ion-exchanged attapulgite (APT) was prepared by aqueous polymerization, using N,N′-methylenebisacrylamide (MBA) as a crosslinker and ammonium persulfate (APS) as an initiator. The effects of ion-exchanged APT on water absorbency of superabsorbent composites in distilled water and in 0.9 wt% NaCl solution were studied. The result indicates that higher cation-exchange capacity (CEC) and lower specific surface area (SSA) of APT treated with various anions are of benefit for improving water absorbency in distilled water. The effects of AlCl3 solution concentration and Al3+-exchanged APT content on water absorbency of the composite were also investigated. The concentration of AlCl3 solution has a great influence on water absorbency of the superabsorbent composite. Al3+-exchange of APT could also enhance reswelling ability of the corresponding composite, which indicates that Al3+-exchange of APT could improve gel strength and gives a direct evidence for its acting as an inorganic assistant crosslinker in the polymeric network. |
