Abstract: In order to find a simple, reliable and applicable method to measure diesel content in water, an experiment to determine the recycling rate of added diesel in water by ultraviolet spectrophotometry was conducted. Key parameters such as the optimum wavelength condition, extraction efficiency of different solvents, different shock extraction time and the amount of the solvent were investigated. The results showed that under the optimum experiment condition, the recycling rate of diesel was 90%-120% with the parallel coefficient of variation less than 10%, which indicated that the recovery test results were fine.
