Изобретение относитс  к аналитической химии и может быть испопьэоаанс дл  опредепешш кобальта фотометрическим методом .This invention relates to analytical chemistry and may be used for determining cobalt by a photometric method.

Известны способы фотометрического определени  кобальта с испо/1ьэованнем ортд ввческих реагещчэв. Лучши т из raix  вл ютс  способы с использованием следующих ергеитчеок х. реагентов: 1 - шггрозо - 2 нафтол, 2 - нитрозо 1 - нафтол, 1 - ннтроэо - 2 - нафтол - 3,6 - нафталин днсупь фок слота (нитрозо - R - соль).There are known methods for the photometric determination of cobalt with the use of the orthorum eryngenum ortus of military reagents. The best of raix are the methods using the following ergech x. reagents: 1 - shgrozo - 2 naphthol, 2 - nitroso 1 - naphthol, 1 - nitroeo - 2 - naphthol - 3.6 - naphthalene dsupoc slot (nitroso - R - salt).

Эта способы наиболее чувствительны и оелвкпготл в Еснользуютс  дл  определени  кобальта в Щ}исутствив меди, никел , ж&лвэа« так как комплексные соединени  по следнвх разрушаютс  минеральными квслотамв, в то врем  как комплексное со данение кобальта устойчиво l .These methods are most sensitive and are not suitable for determining cobalt in copper and nickel, iron and iron since complex compounds of the latter are destroyed by mineral minerals, while cobalt complex formation is stable l.

Штрозо - К - соль содержит сульфо- группу и поэтому хорошо раствор етс  в воде. Нитрозо - К - соль примен ют дл  опредепени  кобальта в водной среде. В к спом растворе реагент обладает желтой О1фао|сой, а комплекс красной.The Stroz-K salt contains a sulfo group and is therefore well soluble in water. Nitroso-K-salt is used to determine cobalt in an aqueous medium. In addition to the solution, the reagent possesses a yellow O1 phosphate, and the complex is red.

Мол рный коэффициент погашени  раствора комплекса кобальта с нитроэо - R сопью при Лдд 415 нм составл ет 3,5 ttO (удельное поглощение 0,60), при 500, когда BnJfflHHe окраски реагента на окраску комплекса незначительно, 1,5 JJIOThe molar extinction ratio of a solution of a cobalt – nitroeo – R syringe complex at Ldd 415 nm is 3.5 ttO (specific absorption 0.60), at 500, when the BnJfflHHe color of the reagent per color of the complex is slightly, 1.5 JJIO

Комплекс кобальта с 1 - ннтроао 2 - - нафтолом имеет оранжевую окраску, его можно экстрагировать различными растворител ми . Мол рный коэффициент погашени  кокгалекса с 1 - ннтрозо- 2 - нафтолом при MAKif 415 ijM составл ет 2,9 1О (удельное поглощение О,49).The cobalt complex with 1 - nitroao 2 - - naphtol has an orange coloration, it can be extracted with various solvents. The molar extinction ratio of cokgalex with 1 - nitro-2 - naphthol at MAKif 415 ijM is 2.9 1 O (specific absorption, O, 49).

Наиболее близким к предлагаемому способу по технической сущности н достигаемому результату  вл етс  способ определе- гии кобальта с реагентом 2 - нитрозо -1 ««афтолом .The closest to the proposed method according to the technical essence and the achieved result is the method of determination of cobalt with the reagent 2 - nitroso -1 "" aftol.

2 - нвтрозо - 1 - нафтол  вл етс  изо|мером 1 -нитрозо-f 2 - нафтола . Компле1вс кобальта с 2 - нитрозо - 1 -  а толом имеет корич ево-розовую окраску . Из двух изомерных н трозоаафголов предпочтение отдают 2 - нитрозо - 1 - нафто2 - nitro - 1 - naphthol is the isomer of 1-nitroso-f 2 - naphthol. The cobalt complex with 2 - nitroso - 1 - has a brown-evolve tolome. Of the two isomeric and throaaafgols, preference is given to 2-nitroso-1-naphto
