At present, there are many methods for separating sulfuric acid from metal ions, such as acid salt separation, oxidation neutralization, direct high temperature melting, and administration, oxidation, acid-base neutralization. Although the above methods are mature, the cost is relatively high, and the operation is complicated, and it is not guaranteed to completely separate the acid from the metal ions.
Membrane separation, as a relatively new technology, has advantages that other methods cannot match. The following is a brief introduction to the advantages of membrane separation technology for separating sulfuric acid and metal ions.
Separation of sulfuric acid and metal ions by membrane separation technology:
1. The membrane separation
device can separate substances having a molecular mass of several hundred;
2. Since the membrane separation does not undergo a phase change, the energy consumption is low;
3. The operating conditions are mild and can be carried out at normal temperature;
4. It is easy to operate. It is efficient and small.
