Discussion on determination of petroleum reference materials by portable ultraviolet oil meter
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.
