Abstract
Both organic and inorganic forms of mercury are analyzed by a modification of the classical dithizone method in the range 0-50 microgram. The separation of mercury from the bulk of interfering ions such as Cu(+2), Fe(+3), B1(+3), Mg(+2), Ca(+2), and Na(+) can be accomplished simply by use of chelating resins. No satisfactory method of separating inorganic mercury compounds from organomercurial compounds by differential elution was found. Mercury is not appreciably volatile in hot oxidizing acidic solution and the elaborate refluxing systems of the standard dithizone method are unnecessary. (Author)
