Abstract. A method for multi-cell laser-fluorescence detection of a small amount of oil pollutants in water, as well as for measuring the concentration of such pollutants in water samples is developed. A technique is proposed for adaptively setting the length of the laser beam path through liquids in samples under investigation, which makes it possible to determine both the average total contamination value for the samples and contamination in each sample. A mathematical justification is presented, an algorithm for implementing the method is compiled, and a variant of the cuvette constructing with the implementation of adaptive tuning of the length of the laser beam path through the liquid in the samples is shown.

Keywords: laser-fluorescent method, pollution, optimization, pollutant concentration, petroleum products, liquid samples
