浸锌溶液中多元金属离子使用消耗的研究

Research on Consumption of Multiple Metal Ions in Zinc Dipping Solution

通过原子吸光度的标准曲线求出使用到不同阶段的浸锌溶液中Zn2+、N i2+、Fe3+、Cu2+的含量;在大量实验的基础上,通过测试浸锌溶液密度,总结出浸锌溶液密度与浸锌溶液颜色及消耗量之间的关系。研究表明:原子吸光度法可以精确计算各种金属离子的实际消耗,浸锌溶液密度监控法可以直观简明的表示浸锌溶液的消耗量。

The content of Zn^2＋ ,Ni^2＋ ,Fe^2＋ and Cu^2＋ is figured out by standard curves of atomic absorbance at different processing stages in the zinc dipping solution. Relations among the density, color and amount used of the zinc dipping solution were induced by measuring the solution densities in the experiments. The results show that the practical consumption amount of various metal ions can be calculated by the method of atomic absorbance; the consumption amount of zinc dipping solution can be estimated by measuring density of the solution.
