| 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 mg•g-1 when C was 0.315 mg•ml-1. |
