利用分光光度法测定水中磷酸盐的不确定度评估分析

Evaluation and Analysis of Uncertainty in the Determination of Phosphate in Water Using Spectrophotometry

磷酸盐作为一种缓蚀剂能够延缓金属容器或管道的腐蚀速度,延长载体寿命。不少学者利用分光光度法对水中磷酸盐的不确定度评估进行测定时,研究对象主要是生活用水或工厂的锅炉用水,研究案例较多,而本文经过调查研究,拟定选用核电厂的常规岛闭式冷却水系统中水分作为研究对象,利用紫外可见分光光度法对其中的磷酸盐不确定度进行评估,得出测量报告和扩展不确定度。

Phosphate,as a corrosion inhibitor,can delay the corrosion rate of metal containers or pipelines and extend the lifespan of the carrier.Many scholars use spectrophotometry to evaluate the uncertainty of phosphate in water,and the research object is mainly domestic water or boiler water in factories.There are many research cases.However,after investigation and research,this article proposes to use water in the conventional island closed cooling water system of nuclear power plants as the research object,and use UV visible spectrophotometry to evaluate the uncertainty of phosphate in it,and obtain measurement reports and extend uncertainty.
