摘要
针对现行HJ 637—2012《水质石油类和动植物油类的测定红外分光光度法》在气田回注水石油类测定过程中存在的空白值高、试剂有毒、萃取率低等问题,探讨四氯化碳选取、萃取分层静置时间、萃取剂替代、是否经硅酸镁吸附等试样制备和数据测定影响因素,在保证测定结果准确度的前提下,对石油类测定的操作技术进行了一些改进。
Aimed at the problems of higher blank value,poisonous agent and low extraction efficiency in the process of determining petroleum oils in gas field reinjection water by the standard 'Water Quality-Determination of Petroleum Oils and Animal and Vegetable Oils-Infrared Spectrophotometry'(HJ 637—2012),several influence factors about specimen preparation and data determination,such as the selection of carbon tetrachloride,extraction standing time,extraction agent replacement and whether using magnesium silicate,were discussed and operation techniques were improved on the premise of ensuring the quality.
