AbstractAbstract
[en] Method for photometric determination of molybdenum in complex alloys on the iron basis having high content of molybdenum is suggested. Molybdenum is transformed to a water-soluble coloured complex by N-benzoyl-2-sodium-sulfonate-N-phenyl-hydroxylamine (BSSPHA) at a H+ ion concentration from 0.1 to 2.0 gxion/l. Effect of large ions (3) almos amounts is eliminated with adding 0.13-0.14 g muriatic hydroxylamine to the reaction mixture. Rectilinear dependence of optical density of solutions on the Mo concentration in the ranges from 100 to 2000 μg in 25 ml finite volume was observed under chosen conditions. Color of the Mo - BSSPHA complex is stable during several days. Fe(2) doesn't interfere with the determination in any quantities, V(5) interfers at a content over 500μg, Ti > 1000μg Duration of 10 sample analysis constitutes 78 hours. The method possesses high accuracy (+-0.1 relative error) and good reproductivity

AbstractAbstract
[en] A method is proposed for separating niobium from a number of elements by sorption of niobium on AV-17 anion-exchanger with subsequent desorption, characterized by the fact that for separating small quantities of niobium from large quantities of titanium, vanadium and molybdenum an ammonium molybdate solution and a hydrochloric solution of molybdenum (5) are preliminarily introduced into the starting product; the resulting blue-coloured niobium-molybdenum heteropolycomplex is sorbed from 0.30-0.35 N sulphuric acid medium on AV-17 anion-exchanger in SO4-form with subsequent washing of the resin with sulphuric acid solution and desorption of niobium by a potassium hydroxide solution

AbstractAbstract
[en] A spectrophotometric method has been developed of determining V, Ti, Mo with sulphobenzoylphenylhydroxylamine. Co, Ni, Cr(3), Fe(2), Cu, Al, Mn, Nb, Ta, La do not interfere. The influence of iron(3) is eliminated by reduction or masking with fluoride and phosphate ions. The effect of PH on complexing is studied. The elements can be determined in alloys without preseparation. The procedures are highly selective and express
