eng	Effect of Water Conductivity on Chlorofyline Reaction with Free Radicals	Chlorophyllin (sodium-cuprum salt of chlorophyll) is able to take part in oxidation - reduction reactions. This ability is used in method for measurement of free radicals (Sevapharma comp.). We were interested how the analytical conditions of the reaction are influenced by different conductivity (G) of water used in this reaction. Four different samples of water were tested (the range of G = 0.1 - 14. microS). The characteristics of absorbance spectra of standards were estimated using Diode-array spectrograph HP 8452 A, Hewlett Packard, USA to compare to each other. The best results were obtained using the water of low conductivity (G = 0.1 microS). The reaction of chlorophyllin and free radicals seems to be competitive one in this conditions and the presence of other ions (able be donators of electrons, too) resulted in the broad of spectra maximum.	free radicals, chlorophyllin, water conductivity
