Abstract
In order to know the absorption performance of Acrylic gel fiber(AGF) on heavy metal ion and provide theoretical basis for its application research on sewage disposal area, Effect of CuSO4 solution temperature, concentration, PH, absorbing time and Na+ concentration on absorption properties were researched. The investigations showed that with increasing of solution temperature, absorption of Cu2+ increased first and then decreased. Absorbed amount of Cu2+ decreased gradually with the reduction of PH value in acidic solution. With CuSO4 solution concentration uprising, absorption capacity of AGF increased. With absorption time prolonged, absorption capacity increased rapidly first and then turned to ease gradually. Absorbed amount of Cu2+ reduced sharply to almost zero with the concentration of Na+ increased. The absorption behavior of Cu2+ and water molecule is highly correlated.
