1. Способ экстракционного концентрировани  ниоби , например, дл  аналитического определени , включаюш;пй экстрагнрова ие его из впинокнслого раствора органическим растворителем в присутствии реагента, выбранно3 го из р да алкилпроизводных диантипирилметапа , отличающийс  тем, что, с целью увеличеии  степепи и селективпости коицентрировани , в качестве растворител  берут смесь дихлорэтана, четыреххлористого углеро-5 да и петролейиого эфира, а в качестве реагеита - ундецилдиантипирилметан. 4 1. A method of extraction concentration of niobium, for example, for analytical determination, including the extraction of it from a pinch solution with an organic solvent in the presence of a reagent selected from a number of alkyl derivatives diantipyrylmetap, characterized in that, in order to increase the degree and selectivity of co-centration, the solvent is a mixture of dichloroethane, carbon tetrachloride-5 da and petroleum ether, and undecyl diantipyrylmethane as the reagent. four 2. Способ по п. 1, отличаюпдийс  тем, что пиобий экстрагируют из 15-20%-ного раствора винпой кислоты, содержащей 10- 15% перекиси водорода, смесью хлороформа, четыреххлористого углерода и петролейного эфира, вз тых в объемных соотношени х ( 1-2):(1-3): (1-4).2. The method according to claim 1, characterized in that the pyobium is extracted from a 15-20% vinpoic acid solution containing 10-15% hydrogen peroxide, a mixture of chloroform, carbon tetrachloride and petroleum ether, taken in volume ratios (1 -2) :( 1-3): (1-4).
