Description

Method for photometric determination of 10-2-10-4% tin with p-nitrophenylfluorone in niobium pentoxide, which is noted for rapidity, accuracy and good reproducibility, has been developed. The method is based on niobium pentoxide dissolving in the mixture of concentrated sulfuric acid and potassium sulfate, distribution separation of tin admixture in the form of halide and its successive photometric determination
