A process of separatory determination of monochioroacetic acid (M. C. A.) and monoiodoacetic acid (M. I. A.) by use of ion exchange resin has been investigated. A strongly basic R-NO3 type resin, Amberlite IRA-410, of 100-150 mesh size was used for the test.The adsorbed acids were liberated by using NaNO3 as a liberating agent in order of M. C. A.and M. I. A. The effluent was hydrolyzed with alkali and the Cl- or I- liberated was determined by titration with Volhard's method to give respective acid content.By application of design of column based on a plate theory, the design of column size was made for a complete separation of them and this was applied for a general separatory method. Quantitative determinations were carried out on various samples prepared under different conditions and satisfactory results were obtained.
