Express Uv-Photometry Method for Determination of the Oil-Compounds Content in Water

Abstract

A new UV-photometry method is proposed for express determination of the oil-products content in water. It does not require long samples preparation and expensive lab equipment but still ensures accurate determination of the dissolved oil-products content. The method is based on the characteristic pattern of the oil-product---water spectra and the peak wavelength. We suppose that the oil-product---water solution has spectrum that corresponds to the spectrum of 1,3,5-trimethylbenzene. A calibration equation connecting optical density of the oil-product---water solution and its concentration has been proposed.
