An organic selenide is decomposed with an oxidizing mixture containing an excess of halogen. Selenium is determined gravimetrically as the metal.The same oxidizing mixture is used for the decomposition of an organic mercury compound commonly used as a seed disinfectant.A method is described by means of which elements difficult to separate may be determined by using two analytical methods followed by simple algebraic calculation for the unknowns.Solid calcium acetate is used to retain the phosphorus on ignition of soybean oils.
