The effect of chloride concentration at pH 0 and 3 has been explored. The results in both solvents follow a similar pattern. At pH 0 and in the absence of chloride, only one anodic peak is observed corresponding to the dissolution of copper metal as MEG is therefore purified of impurities (e.g. diethylene glycol) by passing the stream through an ion exchange column.
