COMPARISON OF NON DISPERSIVE INFRARED AND VISIBLE SPECTROPHOTOMETRY DETERMINATIONS OF OIL IN WATER

摘要

Results of a study using a visible spectrophotometer as an alternate method to infrared spectroscopy for determining concentrations of different oils (standard mineral oil, canola oil, Bright-Edge 80 cutting oil) in water are presented. A statistical analysis comparing the two methods showed that the differences in the concentrations of oil determined using infrared and visible spectrophotometers in the case of three oils were found not to be statistically significant.
