硫酸镍浓度的在线自动测试

Study of Automic Analysis During Production Line of Nickel Surfate

  • 摘要: 研究了化学镀镍工艺过程镀液中硫酸镍浓度的在线自动测试,采用连续流动分光光度的原理研制出了在线自动测试仪。通过对标准硫酸镍溶液的测试得出了硫酸镍浓度与吸光度关系的回归方程。通过对不同镀液的测试,该测试仪测试的标准偏差小于2%,与化学分析方法相比的误差小于3%,并可将测试时间缩短至6min,该测试系统完全适用于化学镀镍生产线上硫酸镍的在线自动测试。

     

    Abstract: The automic analysis during the production line of nickel surfate on plating baths of electroless nickel plating process is given in this paper.Using the principle of continuous flow spectroptometry,the instrument of automic analysis on production line is developed.The regression equation between the nickel surfate concentration and absorbance is abtained through the standard concentration of nickel surfate being determined.The standard deviation of the instrument is less than 2% and the error comparing to the chemistic analystic method is less than 3%.The analytic time only 6 minutes.The instrument completely fits the automic analysis of nickel surfate during electreless nickel plating production line.
