In some cases, for instance, in the electrolysis of steam into hydrogen and oxygen at high temperature, the opposite is true and heat energy is absorbed. This heat is absorbed from the surroundings, and the heating value of the produced hydrogen is higher than the electric input.

Chlorination byproducts (CBPs) are harmful to human health and the environment. Their formation in chlorine mediated electro-oxidation is a concern for electrochemical urine treatment. We investigated the formation of chlorate, perchlorate, and organic chlorination byproducts (OCBPs) during galvanostatic (10, 15, 20 mAcm–2) electro-oxidation of urine on boron-doped diamond (BDD) and

The aim of the present study was to investigate the electrochemical formation of active chlorine and its subsequent use for the degradation of the pesticide fenobucarb. Initially, the process of electrochemical active chlorine production was investigated using an electrochemical flow-cell with a Ti/RuO2 plate electrode. The contribution of four main factors (chloride concentration, current

How is electrolysis used in the industry?

Electrolysis can be used, to produce a very pure metal. For example, copper can be purified up to 99.98% by electrolysis. The disadvantages of electrolysis are as follows. Electrolysis may cause pollution. Electrolysis is an expensive process because it requires

The results of an experimental study on electrochemical disinfection of water are presented. Attention was paid to the behaviour of chlorine compounds during electrolysis of water containing chlorides, with particular regard to the selectivity of the process towards the production of oxidising agents. Two reactor configurations were tested: a stirred tank cell and a filter press cell inserted

Photo

Indeed, some chlorine photolysis is expected even in atmospheric waters (Nowell and Hoign 1992a, b). Thus the simultaneous UV irradiation of mixtures that contain reactive chlorine will result in photolysis of the species HOCl and OCl − at approximately the same rate, with their depletion being proportional to the irradiation time (Nowell and Hoign 1992a ).
