Au radioactive tracer method . the effect of several variables such as stripping agent concentrations , the volume ratio of stripping agents to gold loaded organic phase and the continuous extraction after stripping was studied under 20 . it is found that nh 等对季铵盐载金有机相的反萃,考察了反萃剂的浓度有机相与反萃剂的体积比等对反萃率的影响。
The orthogonal experiment has been used to optimize the electrolyte composition and the craft parameters , with the increasing of the main salt and reducing agent concentration in the electrolyte , the electroless plating coating ’ s adhesive strength and the coverage ratio also increase ; increasing the complex agent content , the electroless plating coating ’ s adhesive strength and the coverage ratio exist the maximum value ; the electroless plating deposition rate distinctly increases when the electrolyte temperature and the ph value were increased , but the increasing of temperature and ph value affects the electrolyte ’ s stability 采用正交实验对镀液成分、工艺参数进行了优化,随着镀液主盐、还原剂添加量的增加,镀层结合强度及其覆盖面依次增强,随着络合剂添加量的增加,镀层结合强度及其覆盖面先增加然后减少,随着镀液温度及其ph值的升高,化学镀沉积速度明显提高,但影响镀液的稳定性。
