Original Abstract

This work is focused on the optical emission spectroscopy observations of the DC non-pulsed diaphragm discharge in various water solutions of selected organic dyes (Direct Blue 106 and Solvent Yellow 94), a mixture of humic acids and alkaline metals. The emission intensity dependencies of hydrogen and oxygen spectral lines on initial conductivity are studied and compared also with respect to the initial solution conductivity. The hydrogen and oxygen intensities increase more or less linearly with the increasing solution conductivity. The oxygen emission is more or less independent on the used electrolyte in the salt. Additionally, the rotational temperature is calculated from the OH radical spectrum for the investigated electrolytes and it is in the range of 500-900 K in the depending on the solution initial conductivity. The dependence of emission intensity on the electrolyte kind is not clear.
