| titleOfInvention | Method for recovering and purifying waste sulfuric acid solution |
| abstract | A method for recovering and purifying a waste sulfuric acid solution includes steps of: adding a coupling agent (m) to the waste sulfuric acid solution, and mixing uniformly to obtain a mixture (a); adding a coupling agent (n) to the mixture (a), and mixing uniformly to obtain a mixture (b); and adding a synergistic agent to the mixture (b), thoroughly stirring and filtering to obtain a purified sulfuric acid solution. The method adds the coupling agent and the synergistic agent to the waste sulfuric acid, and a removal rate of the heavy metal ions in the waste sulfuric acid can reach 99%. The purified sulfuric acid solution can be recycled. The method is simple to operate, and can remove a wide variety of heavy metal ions such as copper, zinc, lead, mercury, nickel, iron, cadmium and manganese in the waste sulfuric acid. |
