  • DETERMINATION OF TOTAL CRUDE OIL IN WATER BY ABSORBANCE SPECTROPHOTOMETRY
    Publication number: 20230273120
    Abstract: A method for quantifying a crude oil in water is provided. The method includes selecting an ultraviolet/visible (UV/Vis) wavelength to perform a measurement, preparing calibration solutions in xylene, and preparing a calibration curve from the calibration solutions. A sample is prepared including extracting the crude oil from the water in a two-phase separation with xylene. An absorbance of the sample in the xylene is measured at the UV/Vis wavelength. A concentration of the crude oil in the water is calculated from the absorbance.
    Type: Application
