Description

A quick and convenient procedure for microdetermination of mercury contained in various materials was established. The method involved a combustion of the materials in a steel oxygen bomb. The samples were burned in the oxygen-filled bomb and the combustion products were absorbed in 1.0 N nitric acid. Mercury was extracted with dithizon solution. The mercury dithizonate thus formed was chromatographically separated using an aluminum oxide column, and was determined colorimetrically. The method is recommendable for quick analysis of voluminous samples having low mercury content. By this method, mercury recoveries from rice bran, which contained mercury at levels between 0.5 and 1.5 ppm, averaged 93%. Unpolished rice, vegetable oil, hair, brain and internal organ of lives as well as rice bran were analyzed.
