Study on the Degradation of Polyacrylic Acid-Sodium Alginate Absorbent Resin

Polyacrylic acid-sodium alginate superabsorbent degradation properties were studied by soil burial method and fungi growth method.Experimental results showed that Polyacrylic acid-sodium alginate high absorbent resin had a good biodegradability to degradation of soil and specific fungi.Polyacrylic acid-sodium alginate superabsorbent 65 days after being embedded in the soil,the degradation rate could reach 43%.Degradation by fungi,50 days later,the degradation rate could reach 60%.
