磷钼蓝分光光度法测废水中磷的不确定度

Determining Uncertainty of Phosphorus in Wastewater by Using Phosphomolybdate Blue Spectrophotometric Method

对废水中的磷用钼蓝分光光度法进行了测量,对测量过程的不确定度进行了分析,找出了影响不确定度的因素,对不确定度进行评估,给出不确定度,以如实反映测量的置信度和准确度,提出了在检测过程中应采取一些技术改进措施。

This article determines the uncertainty of phosphate in wastewater by using phosphomolybdate blue spectrophotometric method, and analyses the uncertainty in the measurement process to identify the influencing factors. Besides, the article also evaluates the uncertainty, gives the results which reflect the true confidence level and accuracy of measurement, and suggests that it should take a number of technical improvements in the detection process.
