Изобретение относитс к области аналитической химии, в частности, к фотометрическим способам определени фольфрама в сплавах на основе ванади .This invention relates to the field of analytical chemistry, in particular, to photometric methods for determining tungsten in vanadium-based alloys.
Известен способ фотометрического определени вольфрама, включающий введение органического реагента из группы оксипропзводных бензопирана и восстановител в анализируемый раствор.A known method for the photometric determination of tungsten includes the introduction of an organic reagent from the group of hydroxypropane benzopyran and a reducing agent into the solution being analyzed.
Цель изобретени - обеспечит1 возможность определени вольфрама в сплавах на основе ванади .The purpose of the invention is to provide the possibility of determining tungsten in vanadium-based alloys.
Это достигаетс тем, что в качестве реагента берут гематоксилии, а в качестве воссгановител - смесь гидроксиламина с аскорбиновой кислотой (весовое соотношение 1:1-5:1).This is achieved by taking haematoxyls as a reagent, and a mixture of hydroxylamine with ascorbic acid (weight ratio 1: 1-5: 1) as reagent.
Иример. Навеску сплава 0,1 г на основе ванади раствор ют в 30 мл смеси сол ной и азотной кислот и вынаривают с 10 мл серной кислоты (1 : 1) до наров серной кислоты.Irimer. A 0.1 g sample of vanadium based alloy is dissolved in 30 ml of a mixture of hydrochloric and nitric acids and extracted from 10 ml of sulfuric acid (1: 1) to sulfuric acid.
