Özet:

 

The flow injection speciation of manganese in aqueous  solution using a spectrophotometry method of detection is presented.   Manganese (VII) can be determined spectrophotometrically at 308 nm  after the reaction with Sym-diphenycarbazide in buffered at pH = 3.05  with phosphate.  Under the optimized conditions, total manganese  concentration can also be determined after oxidation of Mn2+ to  MnO4- and then Mn2+ concentration can be calculated from the  difference.  The linear range of determination is 0.047-4.50 mg/l with  a 3s detection limit of 31 m g/l.  The proposed method is  applied to the determination of MnO4- and Mn2+ in effluent  streams and foods with a relative standard deviation better than  1.85%.  A sampling frequency of up to 24 h-1 can be achieved.   Interfering ions can be removed by an ion-exchange column built into  the flow injection system.
