共振散射光谱法测定酸性镀铜液中的氯离子

Determination of chloride ions in acid copper plating bath by spectroanalysis of resonance light scattering

讨论了乙二醇用量、硝酸银用量、酸性镀铜液(底液)用量、硝酸用量、时间及试剂加入顺序对共振光散射强度的影响。该方法测定酸性镀铜液中的氯离子,线形范围较宽,灵敏度和精密度较高,操作简单,能满足实际生产的要求。

Effects of time, order of adding reagents, contents of ethanediol, silver nitrate, acid copper plating bath and nitrate on scattering intensity of resonance light were studied. The spectroanalysis is applicable to determine chloride ions with advantages of wide linear range, high sensitivity and precision, simple operation, which can meet the demands of practiced production.
