| Abstract: |
| whether additives can make the crystalline surface of cathode zinc become compacter, can have effect on current efficiency and quality of high purity zinc. The experimental results are indicated that the appropriate compound additives are gelatin and TU, and suitable dosage of geltain is 5mg/L and TU is 400 mg/L, the current efficiency is 99.94% and the total content of impurities is 8.151ppm. |
