摘　　要：利用紫外分光光度法建立了咪唑啉缓蚀剂残余浓度曲线。通过分析蒸馏水以及某气田的两种水溶液得知,缓蚀剂质量浓度在0～100 mg/L范围内,吸光度与质量浓度成正比且线性关系较好,可以使用紫外分光光度法对油气田咪唑啉缓蚀剂残余质量浓度进行日常快速检测。Residual concentration curve of imidazoline was established by ultraviolet spectrophotometry. Through analysis of distilled water sample and two samples from a gas field, it was found that the absorbance is proportional to the concentration and with good linear relationship when the corrosion inhibitors are in the range of 0 - 100 mg/L. Ultraviolet spectrophotometry can be used for daily rapid detection of residual concentration of imidazoline in oil-gas field.
