摘要

Abstract

The absorbencies (Q) of superabsorbent

prepared from acrylic acid and acrylamide by the solution polymerization method

in Cl- salt solutions were investigated.The results have shown that

Q increased quickly at first and then increased slowly

and at last became constant in NaCl solutions with an increase of swelling time.However

in transitional metal ionic salt solutions

Q increased at first and then decreased with an increase of swelling time.The relationship between adsorption capacity (q) and adsorption time (t) was investigated

a good linear relation between t/q and t was obtained.The relationship between q and the concentration of Fe3+(C) was also discussed

and the largest q was 171 mg8226;g-1 when C was 0.315 mg8226;ml-1.
