摘　　要：文章采用四氯化碳120 min振荡提取,用红外分光光度法,能够较为准确地测定出油田含油污泥中石油类的含量,采用硅酸镁多次吸咐,能有效去除色度和浊度的干扰。经验证,当石油类含量在74.5~1 456.6 mg/kg时,相对标准偏差为0.95%~8.66%,加标回收率为84.7%~108.8%,精密度、准确度均满足实验要求。This paper adopts infrared spectrophotometry method after using carbon tetrachloride for 120 min oscillation extraction,which could accurately determine the petroleum content in oily sludge.The using of magnesium silicate adsorption for many times could effectively remove the interference of chromaticity and turbidity.It was verified when the petroleum content was in the range 74.5 mg/kg to 1 456.6 mg/kg the relative standard deviation was 0.95% to 8.66% and the recovery rate was 84.7% to 108.8%.The precision and accuracy could satisfy the requirements of the experiment.
