Iodinated X-ray contrast media are known for their stability concerning deiodination in the aquatic environment under aerobic conditions. In this study, we demonstrate the abiotic reductive deiodination of the iodinated contrast media iopromide, iopamidol and diatrizoate in the presence of corrinoids. In addition, triiodinated benzoic acid derivativeswith iodine atoms bound at different positions were investigated. Corrinoids like cyanocobalamin (vitamin B12) and dicyanocobinamide served as electron shuttles and as catalysts between the reducing agent (e.g., titanium (III) citrate) and the electron accepting iodinated compound The concentrationdecrease of the iodinated compoundsfollowed first-order kinetics with rate constantkobs depending on the iodinated compound A linear correlation between the rate of iodide release and the corrinoid concentrationwas observed, with deiodination rates for dicyanocobinamide twice as high as for vitamin B12. Reducing agents with a less neg.standardredox potential like dithiothreitol or cysteine caused slower deiodination as the cobalt center was only reduced to its CoII oxidationstate. With a temperatureincrease from 11 to 23°C, the concentrationsof released iodide doubled. A complete deiodination was only observedfor the iodinated contrast media but not for structurally similar iodinated benzoic acid derivatives
