| Abstract: | A method of excitation-emission matrix (EEM) processing is proposed for determining the concentration of polyaromatic hydrocarbons in aqueous media in the presence of an unknown intense background signal exceeding the legitimate signal by a factor of 15–20. The theoretical substantiation and experimental test of the efficiency of the proposed method have been performed with the use an aqueous solution of anthracene as an example. |
