A series of novel superabsorbent hydrogel composites, poly(CMC-g-cl-PAam/Zeolite)
(ZSAPC) were prepared by in situ graft polymerization using a cellulosic backbone,
acrylamide and natural zeolite. The swelling and deswelling behavior of the prepared
composites was evaluated and analyzed by different empirical models. The composite with
optimum water absorption capacity were impregnated with ZnSO4 in situ during
polymerization reaction. Zincated composites showed less water absorption capacity as
compared to non-zincated ones. Zinc release behavior of zincated test hydrogel composites
was studied in water and soil. All the test compositions exhibited non-Fickian or anomalous
transport (0.43 < n < 0.84) and behaved as slow release products.
