A flow-injection manifold has been developed for the spectrophotometric determination of manganese(VII) at 548 nm after extraction into chloroform of the ion-associate, benzyltributylammonium permanganate. The carrier stream was a pH 6 buffer containing 10% (w/v) ammonium fluoride and the reagent st

The reaction of bismuth with various dithiocarbamates was studied and an extraction spectrophotometric method for its determination using flow-injection sample processing was developed. Bismuth was extracted on-line with a chloroform solution of lead tetramethylenedithiocarbamate (TMDTC) and the ab
