Abstract: Diatomite/sodium carboxymethyl cellulose, a kind of organic-inorganic super absorbent polymer, is prepared through aqueous solution polymerization method with sodium carboxymethyl cellulose, acrylic acid, 2-acrylamide-2-methyl propane sulfonic acid (AMPS) as raw materials and diatomite as inorganic additive.The influences of the neutralization degree of acrylic acid, and the contents of diatomite, carboxymethylcellulose sodium and AMPS on the absorption performances of synthesized polymers are studied via single factor test and orthogonal array design methods, and the optimal conditions are hence determined.The absorbent ratio of the resin prepared under the optimal conditions are 1, 695.1 g·g-1 for distilled water and 120.0 g·g-1 for normal saline.The samples are characterized by infrared spectroscopy (IR) and scanned electron microscopy (SEM).
