1 electrolytic acidity is too large or the temperature is too low;
2 current is too strong;
3 product preparation work is insufficient;
4 There is lead salt in the electrolyte.
Approach:
1 neutralizing the electrolyte with a base and heating;
2 adjust the current density;
3 improve the preparation of products;
4 in DK = 0.2 ~ O. The electrolyte was treated at 3A/dm2 for 10-15 h.
Concerned about surprises
