1. a method for collaborative removal and selective recovery heavy metal in waste water positively charged ion and metalloid anion, the steps include:

  • 1) synergistic sorption;

    be adjusted between 3 ~ 10 by the pH value of waste water, then pumps into waste water and is filled with in the adsorption column of sorbent material;

    2) heavy metal cation reclaim;

    adopt dilute acid soln to step

         1) in absorption after sorbent material carry out first stage regeneration;

    3) metalloid anion reclaim;

    adopt dilute alkaline soln to step

         2) complete after sorbent material carry out subordinate phase regeneration.
