水质pH值的测定是环境监测分析中重要并且经常进行的分析项目之一,是评价水质优劣的一个重要参数。pH值测定虽然比较简单,但监测分析中要求准确度和精度比较高,需要分析者具备丰富、扎实的实验技能,否则,稍有疏忽就会造成分析结果的较大误差。 本人根据pH值的环境监测标准分析方法,结合在实验中获得的监测分析技能和经验,在这里就实验中应注意的、与分析质量有关的问题加以阐述。
The determination of water quality and pH is one of the most important and frequently performed analysis items in environmental monitoring and analysis. It is an important parameter to evaluate the quality of water. Although the determination of pH value is relatively simple, but the accuracy and accuracy of the monitoring analysis require a relatively high, analysts need to have rich, solid experimental skills, otherwise, a slight negligence will result in greater errors in the analysis results. According to the analytical method of environmental monitoring standard of pH value, combined with the monitoring and analysis skills and experience obtained in the experiment, I will elaborate on the problems that should be noticed in the experiment and related to the analysis quality here.
