摘　　要：采用紫外分光光度法测定焦炉煤气中的洗油含量。选择223nm为最大吸收波长,洗油含量为0～8.0mg/L,吸光度与洗油含量基本符合朗伯-比尔定律,相关系数R2达到0.9993,加标回收率在96.9%～100.8%。该方法简单、快速、准确。The wash oil content in coke oven gas was determined by UV spectrophotometry. The maximum absorption wavelength was set at 223nm, the wash oil content was 0~8.0mg/L, the absorbance and wash oil content were basically in accordance with the law of Lambert-Bouguer and Beer, the correlation coefficient R2 was reached to 0.999 3, the add mark recovery rate was in the range of 96.9%~100.8%. This method is simple, rapid and accurate.
