摘要
研究了一种用分光光度计检测超纯氨原料无水工业液氨中油含量的测定方法,包括样品的制备,检测原理,检测步骤与检测结果的合理判断;并对一些技术问题进行探讨,该方法能满足超纯氨气生产的需要,并且比较经济适用。
The research on spectrophotometer testing method for the oil content measurement in the NH3 gas which as raw material, including the preparing for the sample, testing theory, concise process, and reasonable judgment for the testing result. Besides, some technical problems were also discussed. It is reported that it＇ s suitable and economical for the indus- trial producing 7N uhra-pure ammonia.
