Rapid Determination of Peroxide Value in Simulated Waste Oil by Near Infrared Spectroscopy
Abstract:The paper presented a method for rapid determination of peroxides value (PV) in simulated waste oil by near-infrared spectroscopy (NIR). The experiment collected 4 standard samples and 32 simulated waste oil samples made up by heating for different time. The content range of PV was 2.6731∼33.6735 mmol/kg. PV quantitative model was established by spectroscopy pretreatment and partial least squares (PLS) regression method. The Coefficient of Determination (R 2), Root Mean Square Error of Cross Validation (RMSECV), Ratio of performance to standard deviate (RPD) of the calibration model was 0.9554, 1.44 mmol/kg, 4.73. The R 2, Root Mean Square Error of predication (RMSEP), RPD of the validation set was 0.9843, 0.966 mmol/kg, 8.01. The results demonstrated that NIR technology could be successfully applied as a rapid method for determining peroxide value in simulated waste oils. For real waste oil samples, pending further validation experiment.
