Determination of phenylmercuric acetate was carried out by addition of 0.05(w/v)% of potassium iodide[131I]solution to form the insoluble iodide of phenylmercuric acetate and measurement of specific radioactivity of the supernatant by a scintillation counter. Determination of phenylmercuric acetate in the range of 0.25-2.0mg. was possible with standard deviation of below 0.025. Presence of a bulking agent does not interfere in the present determination but the presence of chloride ion was found to cause negative error.
