These methods are based on the redox reactions between metal ions such as ferric ion and cupric ion with hydrogen molecule in the presence of colloidal platinum. The released ferrous ion was developed with o-phenanthlorine, bathophenanthroline disul fonate and Ferrozine, on the other hand cuprous ion was developed with bathocuproinedisulfonate. In these methods, ferric ion is superior than cupric ion because of its sensitivity and stoichiometric reaction with hydrogen molecule. The hydrogen molecule proved to decompose hydroxy radical released from Fenton reaction by spectrofluorometry.展开更多
