GRAPHITE FURNACE ATOMIC ABSORPTION DETERMINATION OF Ge (IV) AFTER ITS CLOUD POINT EXTRACTION

GRAPHITE FURNACE ATOMIC ABSORPTION DETERMINATION OF Ge (IV) AFTER ITS CLOUD POINT EXTRACTION

Abstract

In the current study the conditions for cloud point extraction preconcentration of Ge(IV) in the form of a complex with 6,7-dihydroxy-2,4-diphenylbenzopyrylium bromide in the micellar phase of the nonionic surfactant triton X-100 were studied and optimized. It is shown that the introduction of ammonium benzoate into the studied system with a Triton X-100 nonionic surfactant concentration of 0.5 vol.% and adjusting pH to 1.0 leads to the immediate initiation of the formation of a micellar phase at room temperature. The method of graphite furnace atomic absorption determination of Ge(IV) after its cloud point extraction preconcentration as complex with 6,7-dihydroxy-2,4-diphenylbenzopyrylium bromide has been developed. The calibration graph is linear in the concentration range of 0.05-5.5 mg/dm3, and the limits of detection and quantification are 0.015 and 0.05 mg/dm3, respectively. The proposed method has been successfully applied to the analysis of standard reference materials of geological samples, and the relative standard deviation does not exceed 4.9%.

Вивчено та оптимізовано умови міцелярно-екстракційного концентрування Ge(IV) у вигляді комплексу з бромідом 6,7-дигідрокси-2,4-дифенілбензопірилію у міцелярну фазу неіоногенного ПАР тритону Х-100. Показано, що введення в систему бензоату амонію при рН 1.0 та концентрації тритону Х-100 0.5 об.% призводить до ініціювання утворення міцелярної фази за кімнатної температури. Розроблено методику електротермічного атомно-абсорбційного визначення Ge(IV) після його міцелярно-екстракційного концентрування. Градуювальний графік лінійний в інтервалі концентрацій 0.05-5.5 мг/дм3, а межі виявлення та визначення відповідно дорівнюють 0.015 та 0.5 мг/дм3. Запропонована методика апробована при аналізі стандартних зразків геологічних матеріалів, а відносне стандартне відхилення не перевищує 4.9%.
