Abstract
Изобретение относитс к способам определени алюмини в титановых сплавах и позвол ет упростить процесс. Способ включает переведение анализируемого образца в раствор, введение 20-25% глицерина, буфера , уротропина и алюмината и последующее фотометрирование комплекса. Способ позвол ет определ ть алюминий без отделени титана. 2 табл.The invention relates to methods for the determination of aluminum in titanium alloys and allows to simplify the process. The method involves transferring the sample to be analyzed into a solution, introducing 20-25% glycerol, buffer, hexamine and aluminate and subsequent photometric measurement of the complex. The method allows aluminum to be determined without separation of titanium. 2 tab.
Description
Изобретение относитс к аналитической химии и может быть использовано дл определени содержани алюмини в титановых сплавах.This invention relates to analytical chemistry and can be used to determine the aluminum content in titanium alloys.
Цель изобретени - упрощение процесса .The purpose of the invention is to simplify the process.
Пример 1. 0,1 г титанового сплава раствор ют в 30 мл серной кислоты (1:5), добавл ют 10 капель 20%-ного раствора сол нокислого гидроксиламина и выпаривают до паров серного ангидрида. После охлаждени разбавл ют водой, кип т т и перевод т в мерную колбу на 200 мл. 2 мл этого раствора помещают в мерную колбу емкостью 50 мл, добавл ют глицерина (1:2) до концентрации 20%, 15%-ного раствора уротропина до рН 6,0 и 2 мл 0,1%-ного раствора алюминола. Через 15 мин довод т до метки, перемешивают и измер ют оптическую плотность при Я - 540 н/ч.Example 1. 0.1 g of a titanium alloy is dissolved in 30 ml of sulfuric acid (1: 5), 10 drops of a 20% hydroxylamine hydrochloride solution are added and evaporated to sulfuric anhydride vapor. After cooling, it is diluted with water, boiled and transferred to a 200 ml volumetric flask. 2 ml of this solution are placed in a 50 ml volumetric flask, glycerol (1: 2) is added to a concentration of 20%, a 15% aqueous solution of hexamine to a pH of 6.0 and 2 ml of a 0.1% aqueous solution of aluminol. After 15 min, bring to the mark, mix and measure the optical density at I - 540 n / h.
В образце найдено 1,20% алюмини , (известное содержание 1,17%). Ошибка определени равна 2,5%.1.20% aluminum was found in the sample, (known content 1.17%). The detection error is 2.5%.
В известном способе требуетс предварительное отделение титана, что усложн ет и удлин ет анализ.In the prior art, preliminary separation of titanium is required, which complicates and extends the analysis.
П р и м е р 2. Определение провод т так, как описано в примере 1. Содержание глицерина в растворе равно 25%.PRI mme R 2. The determination was carried out as described in Example 1. The content of glycerol in the solution is 25%.
В образце найдено 1,45% алюмини (известное содержание 1,40%). Ошибка определени равна 3,1%1.45% aluminum was found in the sample (known content is 1.40%). The detection error is 3.1%.
П р и м е р 3. Определение провод т так, как описано в примере 1. Содержание глицерина в растворе равно 23%.PRI me R 3. The determination was carried out as described in Example 1. The content of glycerol in the solution is 23%.
В образце найдено 2,38% алюмини (известное содержание алюмини 2,4%). Ошибка определени равна 1%.2.38% aluminum was found in the sample (2.4% aluminum content). The detection error is 1%.
В табл. 1 приведены результаты определени алюмини в титановых сплавах в зависимости от содержани глицерина. В табл. 2 представлены результаты определени алюмини в титановых сплавах в зависимости от используемых буферов.In tab. Figure 1 shows the results of the determination of aluminum in titanium alloys, depending on the glycerol content. In tab. Figure 2 shows the results of the determination of aluminum in titanium alloys, depending on the buffers used.
Предлагаемый способ (в отличие от известного ) позвол ет определ ть алюминий в титановых сплавах без отделени титана.The proposed method (in contrast to the known) allows the determination of aluminum in titanium alloys without separating titanium.
