On the mechanism of electric discharge enhancement of processes for purifying plant fibers from noncellulose substances: Part 2. chemical and electrophysical influence of electric discharge on an aqueous medium—experimental investigations

Resumo

The article deals with analysis of a working environment (water) during electric discharge action. The formation of insoluble and dissolved substances (metal oxides, hydrated forms of metal oxides, and nitrogen compounds) is studied. It is established that after electric discharge treatment, a considerable amount of different chemical compounds originates in the initial aqueous solution. Those compounds can influence the water–solvent structure during hydration. It is shown that there are discharge water treatment regimes that result in a significant change in the water structure and physicochemical properties over a relatively long period (up to 7 min), after which of water recovers its original properties. During this time, the water exhibits increased activity: the intensity of water absorption by capillary structures of both mineral and organic origin increases, as well as the swelling ability of linen fiber structures.
