摘要
油田污水中含油量的测定采用石油醚、汽油等有机溶剂作萃取剂,绘制标准油的标准曲线。通过对几种萃取剂进行研究,发现萃取剂、测试设备的不同可直接导致同一区块标准油曲线的差异。建议应优先使用石油醚作为有机剂,在使用设备上应统一用一种型号的分类光度计。
Organic solvents, such as petroleum ether and gasoline, are used as extracting agents to measure oil content in oilfield waste water and the normal curves of reference oil are plotted. Studies of several extracting agents discover that different extracting agents and instrumentations can directly result in different normal curves of reference oil in the same block. It is proposed that petroleum ether should be preferentially used as the organic extracting a-gent and spectrophotometers of the same type should be used.
