ABSTRACT

A spectrophotometric method was applied for determination of molybdemun in dried lucerne, grains of soya, peas and bean and vitamin-mineral compound - Multi-tabs. The method is based on the reaction between molybdenum (VI) and 2,3,7-trihydroxyphenylfluorone in the presence of benzyldodecyldimethylammonium bromide. In all samples it was possible to determine molybdenum content directly, after mineralization without its preliminary separation. Accuracy of the determination of molybdenum were checked by the method of standard addition, or by comparison with producer data.To establish the precision of the method, the standard deviation and relative standard deviation were calculate.
