EDTA TITRATIONS WITH EXTRACTIVE END-POINTS. I. DETERMINATION OF COBALT
Journal Article

· Analytica Chimica Acta (Netherlands)
A method for the determination of cobalt by the addition of excess EDTA and back-titration with standard cobalt solution is recommended. The titration involves an extractive method of end-point detection, depending upon the appearance of the blue color of the ion-association pair STAPh/sub 3/MeAs!/sub 2/ STACo(SCN)/sub 4/! in chIoroform. The method is therefore suitable for the estimation of cobalt in highly colored aqueous solutions. Average errors are expected to be less than 0.5%. (auth)
