摘 要：The absorbencies (Q) of superabsorbent, prepared from acrylic acid and acrylamide by the solution polymerization method, in Cl- salt solutions were *** 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 ***, in transitional metal ionic salt solutions,Q increased at first and then decreased with an increase of swelling *** relationship between adsorption capacity (q) and adsorption time (t) was investigated, a good linear relation between t/q and t was *** relationship between q and the concentration of Fe 3+(C) was also discussed, and the largest q was 171 mg·g -1 when C was 0.315 mg·ml -1.
