AB  - In this study, the catalytic effect of nitrite on the cobalt complex of acid red 27, which is one of the most important azo dyes today, was investigated. Voltammetric studies were carried out with a Hanging Mercury Drop electrode and pencil graphite electrode using the Cathodic AdsSWV technique in nitrate media. First, in situ formation of the complex was determined by electrochemical method. It was then observed that the voltammetric peak current of the complex increased in the presence of nitrite anions. The deposition time, potential and nitrite concentration were investigated to optimize the conditions for both electrodes.  According to the results, the reaction mechanism of the catalytic effect of nitrite has been proposed.
