Interaction of Electrical Discharge with Water Solutions of Humic Acids

Článek recenzovaný mimo WoS a Scopus

Preliminary results of our research focused on the application of constant DC diaphragm discharge in water solutions containing humic substances are presented in this paper. It has been found out that character of humic acid solution remarkably changes from aromatic to aliphatic, especially in the anode space of the reactor. Presented work extends our knowledge about decomposition of humic substances by the electric discharge in the dependence of solution properties and discharge conditions. Parameters such as initial solution conductivity, electrolyte kind or input power have been investigated. Moreover, substantial effect of pH on humic acid decomposition has been observed. Absorption spectroscopy in UV-VIS region together with fluorescence spectroscopy has been used for the detection of changes in humic solutions.
