除盐水的p H值离线测定的准确性容易受到各方面因素的干扰,影响因素包括电极本身的构造和工作特性,样品的性质,样品测定时环境施加的影响以及样品测量方式带来的误差。实验室通过大量实践,几年来一直对提升除盐水p H值准确性的测定方法进行改进,通过选择合适的测量电极,添加离子强度调节剂,严格控制流量等措施,可以最大程度减少测量误差,提高除盐水p H值离线测量的准确性。
Determining the p H value of desalinated water off-line is susceptible to various factors including structural and operating characteristics of the electrode itself, the nature of the sample, the environmental impact of the sample measurement, and the error associated with sample measurement. Through a large number of practices in the laboratory, the method for improving the accuracy of pH value determination of desalinated water has been improved over the years. Measurement errors can be minimized by selecting suitable measuring electrodes, adding ionic strength adjusting agents and strictly controlling the flow rate, Improve the accuracy of off-line measurement of p H value in desalted water.
