Determination of platinum-group elements in rocks by ICP-MS with external calibration after cation exchange separation of matrix elements by KU-2-8 resin

Abstract: Поступила в редакцию 3 июня 2016 г., после исправления -7 июля 2016 г.Предложена методика определения элементов платиновой группы (ЭПГ) Ru, Rh, Pd, Ir, Pt и Re в геологических образцах в диапазоне концентраций от 0.1 нг/г до 10 мкг/г, а также Os в перидотитах на уровне нг/г методом масс-спектрометрии с индуктивно связанной плазмой с внешней градуировкой и без химического удаления Zr и Hf. Подготовка проб основана на их кислотной деструкции в открытых системах после обжига с последующим доплавлением нерастворим… Show more

“…Analytical studies were carried out in the Institute of Geochemistry, SB RAS and in the Baikalian Analytical Center of Shared Use, Irkutsk Science Center, SB RAS. The contents of PGE (Ru, Rh, Pd, Pt, Ir, and Os), Au, and Re were defined by MS-ICP method at an Element 2 (Finnigan MAT) high-resolution mass spectrometer, with the use of an open acid decomposition and separation of matrix elements on KU-2-8 cation exchanger by the technique from [Men'shikov et al, 2016]. Precision and accuracy as demonstrated by analyzing reference materials, such as Zh-3, RP-1, Jp-1, are better than 10 %.…”
