A recently known method of paper chromatographical separation of o- iodobenzoic acid-/sup 131/I and o-iodohippuric acid-/sup 131/I was found to be in error. The solvent mixture proposed in the method for the efficient separation of the two compounds of similar structure is not only made nonhomogeneous but also brings about no separation. It was also confirmed that no o-iodohippuric acid is convented to o-iodobenzoic acid during the process for Hippuran-/sup 131/ I preparation by isotopic exchange. An alternate method of chromatographical determination or radiochemical purity of Hippuran-/sup 131/I is proposed. (auth)
