Изобретение относитс к аналитической химии, в частности к способам определени свинца фотометрическим методом.This invention relates to analytical chemistry, in particular to methods for determining lead by the photometric method.
Цель изобретени - повышение экс- прессности определени при массовых анализах;The purpose of the invention is to increase the expressiveness of the determination during mass analysis;
Пример 1, В мерную колбу на 25 МП ввод т 0,5 МП 1%-ного раство- ра тиродина, 0,25 мп анализируемого раствора, содержащего 0,5 мкг/мп свинца, 0,5 МП готового комплекса свинца с тиродином состава Me : R 1:2, что составл ет 2% от объе- ма пробы, подкисл ют до рН раствором 0,1 М азотной кислоты, перемешивают и определ ют содержание свинца фотометрическим методом.Example 1 Into a volumetric flask of 25 MP, 0.5 MP of a 1% solution of tirodin, a 0.25 MP of the analyzed solution containing 0.5 µg / MP of lead, 0.5 MP of a finished complex of lead with a thyrodine are introduced. Me: R 1: 2, which is 2% of the sample volume, acidified to pH with a solution of 0.1 M nitric acid, mixed and the lead content is determined by the photometric method.
Найдено О,А мкг/мп +1% РЪ. Врем анализа 5 мин.Found O, A µg / mp + 1% Pb. Analysis time 5 min.
Пример 2о В мерную колбу на 25 МП ввод т 0,5 МП 1%-ного раствора тиродина, 0,25 мп анализируемого раствора, содержащего 4 мкг/мп свинца , 1,25 мл готового комплекса свинца с тиродином, что составл ет 5% от объема пробы, подкисл ют до рН 4 раствором 0,1 М азотной кислоты, перемешивают и определ ют содержание свинца фотометрическим методомExample 2: Into a 25 MP volumetric flask, add 0.5 MP of a 1% aqueous solution of tirodin, a 0.25 mp of test solution containing 4 µg / mp of lead, 1.25 ml of a finished complex of lead with thyrodine, which is 5% from the sample volume, acidified to pH 4 with a solution of 0.1 M nitric acid, stirred and the lead content is determined by photometric method
Найдено 3 мкг/мл ±1% РЬ. Врем анализа 5 мин. Чувствительность спо- соба 4,2 Ю.Found 3 μg / ml ± 1% Pb. Analysis time 5 min. The sensitivity of the method 4.2 Yu.
В таблице приведены данные по вли нию количества готового ком лек- са свинца с тиродином на скорлсть развити цветной реакции сви1 т;а с тиродином.The table shows the data on the effect of the amount of the finished lex-thyrodin lex complex on the development of the color reaction of light and with the thyrodin.
