For the development of a precise determination of boron in nickel steels and alloys, carmine, 1,1'-dianthrimide, chromotrope 2B, and arsenaza II were studied as reagents for the photometric determination of boron. The authors compare them here with respect to sensitivity, selectivity and reproducibility of results, and they refine the optimum reaction conditions. To refine the optimum extraction conditions, the effect of Beta-diol and sodium hydroxide concentrations, ratio of water to organic phase, and shaking time were tested. Study of the distribution coefficients of iron, molybdenum, tungsten, vanadium, titanium and niobium show that boron could be completely separated from these steel components by extraction with Beta-diol solutions. In order to accelerate the dissociation process and eliminate the use of a reflux condenser, the authors studied the effect on the extraction of sulfuric-phosphoric and hydrochloric-nitric-phosphoric acid mixtures at various ratios of components.
