Abstract

Keywords Pilot plant  Green rust  Chromate additions  is lost. The corrosion process renders the need for a high Electrolysis  Surface characterisation  Temperature effect concentration of chromate in the electrolyte and also a decreased current efficiency after the stop and during the build-up of the Cr(III) film [8]. 1 Introduction The influence of different parameters, such as the addition of chromate, changing the temperature, the elec- 1.1 Background trolyte concentration, the pH and the presence of additives, on the performance of the chlorate process has been The sodium chlorate process, with an annual production of reported [7–11]. The current efficiency has been studied in approximately 3.6 million tons of NaClO worldwide, is some publications, but the most common approach is to one of the most important electrolysis processes today. The study the cell or electrode potential and oxygen production process is quite energy intensive, with a power consump- [9, 10, 12–17]. It has also been reported that the time it -1 tion of 4600–5000 kWhton [1]. The main use of sodium takes to reach stable conditions in a chlorate cell or at the chlorate is in the environmentally friendly elemental surface of a chlorate cathode
