Abstract
The paper deals with the application of spectrophotometric method and the sensor for determination of contaminating hydrocarbon impurity presence in waste water. The sensor is designed on the basis of modern element base. For measurement accuracy increase it has computer processing of analysis results for the absorption spectra of liquid (water) media in the ultraviolet wavelength range. The proposed sensor and computer program enabled the study of hydrocarbon impurity presence in the water that is an important factor for continuous monitoring of the environment. The absorption spectra of gasoline, diesel fuel, synthetic motor oil, fuel oil, natural oil are given as the most frequently present as impurities in the water, measured on an automated spectrophotometric sensor model. The use of modern small-sized elements makes it possible to design a small-sized highly sensitive sensor for express analysis of the water quality.
Acknowledgements. The studies were carried out at the Faculty of Laser Photonics and Optoelectronics of ITMO University as part of the master’s and postgraduate work. The authors are grateful to Vera Sitnikova, the faculty member, and Maya V. Uspenskaya, Professor of the faculty, for the possibility of carrying out the UV absorption spectrum measurements for some impurities of interest on the Uniko type UV spectrophotometer for the reliability of the results obtained on our UV spectrophotometer.
