The poly acrylic acid-sodium humate composite super absorbent polymer was synthesized by aqueous solution polymerization through the technology of no nitrogen and not removing polymerization inhibitor in acrylic acid. In the synthesis process, acrylic acid and sodium humate were as monomer. The study results showed that when the neutralization degree of acrylic acid was 60%,the dosage of sodium humate was 1. 0g,the dosage of initia-tor( potassium persulfate) was 55mg, and the dosage of crosslinking agent ( N, N′-methylenebisacrylamide) was 20mg,the highest distilled water-absorbing capacity of the composite super absorbent polymer was 1200g/g.
