Monitoring of chlorine by new method based on FOS in water bodies

Fibre optic sensor (FOS) is used to measure the concentration of total chlorine in samples of surface water, swimming pool water and leachate from MSW landfill. FOS represents new original method which is based on the color of the sample for measurement ofanalyteconcentration. Color sensor converts RGB (Red-Green-Blue) color model to HSV (Hue-Saturation-Value) color model. S and V parameters were used for determination of chlorineconcentrations in selected water bodies. H parameter was used for the calculation of wavelength at which applied sensor measures the concentration of total chlorine. Research was carried out to validate the effectiveness and repeatability of the results obtained with FOS and confirms the capability to use sensor in laboratory controlled conditions. Results obtained with FOS are compared with standard analytical methods (UV-Vis spectrophotometer) to confirm the possibility of using FOS as replacement for standard analytical expensive equipment
