【摘要】 本文采用水相蒸发除去大量的氯离子,用等速电泳法对油田水中短链有机酸进行了定性定量分析。结果表明,油田地层水中有机酸成分主要有甲酸、乙酸、丙酸、丁酸、苯甲酸和乳酸等,本法回收率和相对标准偏差分别在96％～105％和2.4％～7.6％之间。更多还原

【Abstract】 The evaporation of water phase has been used to remove high concentration of chloride anion from oil field water. The performance of qualitative and quantitative analysis of short-chain organic acids was studied in three electrolyte systems on LKB2127 and 1P-2A isotachophoretic analyzer. The dominant component in the oil field water is formic acid, acetic acid.propionic acid, butyric acid, benzoic acid and lactic acid.更多还原
