摘　　要：在突发性水环境污染事件石油类样品的应急监测中,监测数据的准确性和及时性是事故处理的核心工作。因此,体积小巧、方便携带、环境适应性强的便携式紫外测油仪应运而生,逐渐在石油类环境污染应急监测中薪露头角。为了验证便携式仪器监测结果的准确程度,本文采用便携式紫外测油仪根据紫外分光光度法测定水质中石油类标准样品,从透光率实验参比用水以及对市面上常见的三种正己烷中石油类标准物质A、B、C进行了标准曲线及标准样品的测定分析,从而提升便携式紫外测油仪对水中石油类物质监测的适用性,为今后石油类突发应急监测提供依据。The accuracy and timeliness of monitoring data are the core work in the emergency monitoring of oil samples in sudden water pollution incidents.Therefore,the portable ultraviolet oil meter,which is small in size,convenient to carry and has strong adaptability to the environment,is emerging gradually in the emergency monitoring of petroleum environmental pollution,but the actual sample size is not enough,during the test,there are some doubts about whether the parameters(transmittance,standard curve and standard sample)of the automatic ultraviolet oil meter can meet the requirements of the portable ultraviolet oil meter.In order to verify the accuracy of the monitoring results,a portable ultraviolet oil meter was used for the determination of petroleum standard samples in water based on UV Spectrophotometer,the standard curves and standard samples of petroleum reference materials A,B and C in three common n-hexane were determined and analyzed from the reference water for light transmittance experiment,therefore,the applicability of the portable ultraviolet oil meter to the monitoring of petroleum substances in water is improved,and the basis for the future oil emergency monitoring is provid-ed.
