| 摘 要： | 采用重量法分析镀锌钝化液中H2SO4含量并对槽液进行调整时，发现H2SO4含量测得值明显偏高．采用电位滴定法测定该钝化液中H2SO4含量，结果表明，新方法测得的H2SO4含量低得多，更接近真实值，能较好地指导槽液的维护，说明其准确度较好。

| Abstract: | The H_2SO_4 content in the passivating solution of zinc plating determined by weight method is erroneous and much higher than the accurate value. A kind of potentiometry was promoted for determining the H_2SO_4 content in the passivating bath. The results show that the H_2SO_4 content analyzed by the new method is accurate and much lower than that tested by the weight method, and good passivating effects were obtained when the H_2SO_4 content analyzed by the new method was used for maintaining the passivating solution. |
