The present invention concerns a method of optical measurement of an aqueous stream, and of processing the results of the measurement in order to determine the anionic charge of the stream, the method being carried out by measuring the light absorption of the stream and predicting the amount of anionic groups in the stream using a mathematical processing, such as mathematical calculations. Particularly, the method includes the steps of adding an amount of a cationic dye to the aqueous stream, measuring the light absorption spectra of the obtained dye-containing stream, and processing the obtained light absorption spectrum using said mathematical processing in order to obtain the anionic charge. The invention also concerns the use of the obtained spectrum in determining the turbidity of the stream, as well as a device suitable for use in carrying out the method.
