分光光度法对油中微量铜的测定
摘要
在方法的研究中
对pH值、指示剂浓度、样品的回收率等方面进行了条件试验。将该方法与原子吸收光谱法进行了比较
并利用该法将15种油样在3个不同试验室进行了测定。其结果表明
准确度好
误差符合要求。该法操作简单
可以在电厂使用。
Abstract
Presented in this paper is a spectrophotometric method for measurement of trace copper in oil. During the study of this method
various tests were conducted under different pH values
concentrations of indicator and recovery of samples. The results of 15 oil samples being tested in three different laboratories show that this method can be popularized in power utility since it has a higher accuracy and an easy operation.
