Description
Предметом изобретени вл етс способ фотоколориметрического определени железа в титане без предварительного отделени последнего.The subject of the invention is a method for photocolorimetric determination of iron in titanium without first separating the latter.
Способ фотоколориметрического определени железа с помощью суль(|)осалициловой кислоты известен . Одпако этот способ неудобен дЛ определени железа в титане, образуюп1.его с сульфосалици.ловой кис.:ютой в слабокислой среде окрашенный растворимый комплекс, который iieniaeT определению железа.The method of photocolorimetric determination of iron with the help of suly (|) osalicylic acid is known. However, this method is inconvenient for the determination of iron in titanium, which forms it with sulfosalicytic acid: a mixture of soluble soluble complex in the weakly acidic medium, which is iieniaeT for the determination of iron.
Описываемый способ отличаетс от известного тем, что дл св зывани титана в растворе в бесцветный комплекс определение железа ведетс в аммиачной среде, без предварительного отделени титана. Таким образом расп1ир етс объем фотоколориметрнческих определений железа и иск.чючаетс расходование дефицитного реактива ортофенантролина .The described method differs from the known one in that for the binding of titanium in solution to a colorless complex, the determination of iron is carried out in ammonia, without first separating the titanium. Thus, the volume of photocolorimetric determinations of iron is measured and the use of the deficient orthophenanthroline reagent is sought.
Навеску в 0,5 г титана или его сплава раствор ют в 50 мл серной кислоты 1 :о и затем окисл ют азотной кислотой. Раствор переливают в мерную колбу емкостью 100 мл разбавл ют водой до метки. Две пробы по 20 мл раствора отбирают в две мерные колбы емкостью 100 мл, добавл ют по 10 мл серной кислоты и в одну из колб прнлнвают 15 мл сульфосалицнловой кислоты и 15 мл аммиака, доливают водой до метки обе ко.пбы н измер ют 1н-1тенсивность желтой окраски в фотоколориметре . Содержание железа наход т по калибровочной кривой. Способ позвол ет определ ть количества железа от 0,05 до 5i.A weighed amount of 0.5 g of titanium or its alloy is dissolved in 50 ml of 1: o sulfuric acid and then oxidized with nitric acid. The solution is poured into a 100 ml volumetric flask and diluted to the mark with water. Two samples of 20 ml each of the solution are taken in two 100 ml volumetric flasks, 10 ml of sulfuric acid are added each time, and 15 ml of sulfosalicylic acid and 15 ml of ammonia are added to one of the flasks, and they are filled to the mark with water to 1 ml. 1 The intensity of the yellow color in the photocolorimeter. The iron content is found on the calibration curve. The method allows the determination of iron amounts from 0.05 to 5i.
