With zeolite,cellulose,acrylic acid and etc as raw materials,water-absorbent and retaining composites were synthesized by water solution cross-linked polymerization. The characterizations of functional groups of composites were performed with Infrared spectra. Eluviation and evaporation experiments were conducted to study water-nutrient controlling effect of zeolite / cellulose composites. The results showed that there are strong crosslinking polymerization between zeolite,cellulose and monomer. These compo...
