阴离子表面活性剂对油含量测定的影响

Influence of anionic surfactant on determination of oil content

本文采用红外分光光度法对水中不同含量的阴离子表面活性剂对油含量测定的影响进行了研究。实验数据表明,当水中含有阴离子表面活性剂为100 mgL时,对油含量测定|无影响;当阴离子表面活性剂浓度为200 mg/L时,会造成油含量测定值偏高3.38%;当阴离子表面活性剂浓度为400 mg/L时,会造成油含量测定值偏高14.64%;当阴离子表面活性剂浓度为1000 mg/L时,会造成油含量测定值偏高32.43%。

In this paper, infrared spectrophotometry is used to study the influence of different content of anionic surfactants on the determination of oil content in water. The test data shows that when the anionic surfactant concentration is 100 mg/L, it has no effect on the determination of the oil content;when the anionic surfactant concentration is 200 mg/L, the measured value of the oil content will be higher by 3.38%;when the the anionic surfactant concentration is 400 mg/L, the measured value of oil content will be higher by 14.64%;when the anionic surfactant concentration is 1 000 mg/L, the measured value of oil content will be higher by 32.43%.
