摘要
针对常用的测定水中石油类的红外分光光度法,对于不同浓度的样品,如何把握样品采集、试验环境、仪器试剂、样品萃取以及质量控制等多方面的关键环节提出了探讨,并对石油类萃取过程中的温度、次数等的控制进行了试验性研究,为合理控制实验条件,提高测定结果准确性、及时性提出了一些可操作性建议。
The paper investigates the measurement of oil samples of varied concentration through infrared spectro- photometric determination. Emphasis is placed on issues like sample collection, experimental environment setting , instrument and reagent selection, sample extraction and quality control all though the whole processes. Experiments develop to test the temperature, measurements frequency for the extraction of oil samples to provide the suggestions for improvement of accuracy and timely measurement.
