A simple method for the detection of floating oils on water has been proposed. The method is based on two procedures which are collection of the oils on a polymer film and photometric measurement of light absorption in the visible region of the film adhered to the oils. Floating oils of a few microns in thickness on water are effectively adhered to the polymer film, such as polypropylene or polyvinyl chloride. Generally, common oils do not absorb light in the visible region. When a transparent film is used to collect the oils, the absorbance of the film at the visible region increases little or nothing. However, when a translucid film is used, the film is clarified by adhesion of the oils. It is possible to detect the floating oils on water by measuring the absorbance of the translucid film in the visible region (650 nm). An equipment for the detection of floating oils has been designed.
