Although there are numerous reports on the quantitative estimation of mercury in organic compounds, no method is found for rapid and accurate estimation of it for those containing halogen. The present method by the writers consists as follows : the sample is decomposed in a usual type combustion tube, the mercury evolved is led, through a calcium oxide layer, into a collector containing nitric acid and the solution is titrated with ammonium thiocyanate. The procedure is finished in 35 minutes for one sample and the presence of chlorine or bromine gives no disturbance in the estimation.
