Chloroform recovered by the proposed method was suitable for analytical purposes; there was no change in the optical densities of dithizone solutions prepared from it after 5 days storage in the dark at ,,, 5 ~ A batch of dithizone residues contaminated with phosgene gave a satisfactory product when purified by the proposed method. The time taken for the proposed method was approximately 2 hours as against 5 hours for that of MULLIN AND RILEY. Although the proposed method has only been applied to residues containing lead and zinc dithizonates, it should be applicable to other dithizonates provided they are easily dissociated and contain metals which react with EDTA.
