“…The instrumental quantification limits of Pt, Pd, and Rh (calculated as three times the standard deviation of ion counts obtained from the 3 % HNO 3 solution measured 12 times, divided by the sensitivity determined using the 10 ng ml −1 PGE standard solution) were 3, 10, and 4 pg ml −1 , respectively. Detailed analytical results for the reference materials and procedural blanks are described elsewhere (Li et al 2011 (Simitchiev et al 2008). 180 Hf was monitored to assess the potential interference of HfO species on Pt (Simitchiev et al 2008).…”

Purpose Human exposure to particulate matter emitted from on-road motor vehicles includes complex mixtures of heavy metals from tyres, brakes, part wear, and resuspended road sediment. The purpose of this study was to determine the concentrations of 14 platinum-group and other trafficrelated heavy metals in road sediment within the metropolitan area of Guangzhou, China, with a view to identifying their sources and assessing the extent of anthropogenic influence on heavy metal contamination of road sediment. Materials and methods Thirty-five samples of road sediment were collected. The concentrations of Cr, Mn, Ni, Cu, Zn, La, Ce, Mo, Cd, Pb, Ba, and Rh were measured by inductively coupled plasma-mass spectrometry. Pt and Pd were analyzed by isotopic dilution-inductively coupled plasma-mass spectrometry. Multivariate statistical analysis and enrichment factor methods were employed to identify the sources of these heavy metals and to assess anthropogenic influences on their occurrence. Results and discussion The mean concentrations of Pt, Pd, Rh, Cr, Mn, Ni, Cu, Zn, La, Ce, Mo, Cd, Pb, and Ba in the road sediment samples were 68. 24, 93.15, 23.85, 147.5, 712.3, 47.24, 177.5, 1254, 47.50, 96.62, 4.91, 3.00, 198.1, and 641.3 ng g −1 , respectively. Very weak to significant linear positive correlations were found among the various heavy metals. The elemental composition of road sediment was dominated by five principal components. Three clusters were identified through cluster analysis, and enrichment factors were calculated relative to soils in China. The sources and degree of contamination of the heavy metals are discussed based on the results. Conclusions The mean concentrations of heavy metals are higher than background values, especially for Pt, Pd, Rh, Cd, and Zn. Four main sources are identified: (1) Pt, Pd, and Rh were derived from traffic sources; (2) La, Ce, Mn, and Ba were derived mainly from natural sources; (3) Cr, Ni, Cu, Mo, Cd, and Pb showed mixed traffic-industry sources; and (4) Zn originated mainly from industrial sources. Enrichment factor analysis supported this source identification and further indicated that contamination of road sediment in Guangzhou is extremely high for Pt, Pd, and Rh; moderate to very high for Cd, Zn, Pb, Cu, and Mo; and minimal for Cr, Ni, La, Ce, and Ba.

“…The concentrations of Hf, Cu, and Pb exceed the concentrations of PGMs by several orders of magnitude, resulting in difficulties with the detection of PGMs by ICP MS [48,49]. Preliminary treatment with HCl can result in a decrease in base metal content in the final examined solution, without PGM loss [93]. The application of mathematical correction [48,205], dry plasma conditions obtained by modification of sample introduction into the plasma [53,205,207,208], dynamic reaction cells [97], sector field instruments [53], and chemical separations [50,209] are used for the elimination of interferences in the detection of the metals in airborne matters by ICP MS. Quantitative separation and preconcentration of Pt from dust samples (CRM BCR-723) by cloud point extraction prior to ICP MS detection has been reported [210].…”

Иркутск, Фаворского, 1А aisu@igc.irk.ru 2 Иркутский государственный технический университет Российская Федерация, 664074, г. Иркутск, ул. Лермонтова, 83. Поступила в редакцию 7 октября 2014 г, после доработки -29 октября 2014 г.Предложены методики рентгенофлуоресцентного определения платины, рения и пал-ладия в катализаторах на основе оксида алюминия. Содержание Pt и Re в платинорениевых катализаторах варьировало в диапазоне 0.2-0.5 % мас., содержание Pd в палладиевых ката-лизаторах -от 0.4 до 2 % мас. В качестве аналитических линий выбраны Pt Lα, Re Lβ 1 и Pd Kα. Материал платинорениевых катализаторов (2.5 г) прессовали в виде таблеток с добавлением синтетического воска (0.1 г) в качестве связующего вещества. Пробоподготовка палладиевых катализаторов заключалась в горячем прессовании смеси 0.3 г катализатора с 2 г порошковой целлюлозы. Для построения градуировочных характеристик использовали образцы катализа-торов с известным содержанием определяемых элементов и образцы с аттестованными со-держаниями. Коэффициент вариации, характеризующий внутрилабораторную прецизионность, составил для Pt, Re менее 0.5 % и для Pd -1.6 %. Результаты рентгенофлуоресцентного опре-деления сопоставлены с содержаниями в стандартных образцах и с результатами спектрофо-тометрического определения. Погрешность рентгенофлуоресцентного определения состави-ла для Pt, Re ~0.01 % мас. при содержаниях 0.2-0.4 % мас., для Pd -0.02 % мас. в диапазоне 1-2 % мас. и ~0.01 % -при содержании Pd менее 0.5 % мас.Ключевые слова: рентгенофлуоресцентный анализ, катализаторы на основе оксида алюминия, платина, рений, палладий.Айсуева Татьяна Санжаевна -кандидат химических наук, научный сотрудник Ин-ститута геохимии СО РАН.Область научных интересов -рентгенофлуоресцентный анализ, анализ вещества в геохимии, анализ объектов окружающей среды.Автор более 60 научных публикаций.Финкельштейн Александр Львович -доктор технических наук, заведующий лабо-раторией рентгеновских методов анализа Института геохимии СО РАН.Область научных интересов -рентгеноспектральный анализ, рентгенофлуорес-центный анализ, анализ вещества в геохимии.Автор более 100 публикаций.Белозерова Ольга Юрьевна -кандидат химических наук, старший научный со-трудник Института геохимии СО РАН.Область научных интересов -рентгеноспектральный электронно-зондовый ми-кроанализ природных объектов, растровая электронная микроскопия, экология, ис-следования микрочастиц, минералогия.Автор более 100 научных публикаций, в том числе 1 монографии.Скорникова Светлана Афанасьевна -кандидат химических наук, доцент физико-технического института ИрГТУ.Область научных интересов -физическая химия, синтез и исследование свойств катализаторов.Автор более 80 научных публикаций
