Influence of electrode material on the electrochemical behavior of the absorbing solution of the quinhydrone method of gases purification from hydrogen sulfide

The electrochemical behavior of carbonate solutions of the quinhydrone at different concentrations 1, 5, 10, 20, and 30 g/dm3 at the exposure time 0…12 days on different electrode materials - Ni and Au were studied by the cyclic voltammetry (CV) method. The catalytic properties of gold different from nickel in the anodic oxidation reactions of the quinhydrone catalyst are noted.

THE INFLUENCE OF EXPOSURE TIME ON CHANGING OF THE PROPERTIES OF THE SODA SOLUTION OF QUINHYDRONE DURING THE QUINHYDRONE CATALYST PREPARATION

In the quinhydrone method of gases purification from hydrogen sulfide as an oxidizer of chemosorbed hydrogen sulfide, a quinhydrone catalyst is used. It is obtained by oligomerization of benzoquinhydrone in an alkaline solution. The oxidation-reducing properties of the quinhydrone catalyst are very important for the process of gases purification from hydrogen sulfide.
