Chlorine dioxide - Registration Dossier - ECHA
{Includes more useful info, as well} "Bubnis (2009) reported the loss of chlorine dioxide in ballast water. This experiment clearly demonstrated that any chlorine dioxide residuals that might be present following the treatment of ballast water will quickly be consumed by dilution and demand. Chlorine dioxide and its transformation products (chlorite and chlorate) showed similar demand features when tested in divers waters. The author observed an initial fast demand for chlorine dioxide along with a slower continuing loss of chlorite and chlorate ions." "Photodecomposition of chlorite in aqueous solution is rapid with a half life of about 10 minutes depending on concentration. Oxygen, chloride and chlorate are produced as stable end-products with the formation of chlorine and chlorine dioxide as intermediates."
