“…The interfering ions were investigated at a fixed concentration of 1 mM, which is a hundred times in excess compared to that of ReO 4 ions. The selectivity coefficient (log k (i,j) amp ) for all the interfering anions studied are listed in Table 2 calculated using the Eq (7) [37]: (7), where i and j correspond to the ReO 4…”

Voltammetric responses associated with the simple reaction of perrhenate anions transfer across polarized micro-interfaces between two immiscible electrolyte solutions (micro-ITIES) was investigated, and their sensing applications were demonstrated. The micro-ITIES array was formed at polyethylene terephthalate membranes containing a 196 microhole array of radius 10.0±0.1 μm using a femtosecond laser. The characteristics of perrhenate ions transfer at the water/2-nitrophenyloctyl ether interface were first investigated using cyclic voltammetry (CV). CV was used in the estimation of some of the perrhenate anions thermodynamic parameters, such as the formal transfer potential and the Gibbs transfer energy. The technique of alternating current stripping voltammetry (ACSV) was also utilized to improve the sensitivity of the perrhenate anion detection. Under optimized preconcentration and detection conditions, a limit of detection of 0.3 μM with a wide linear dynamic range extending from 1.0 to 100 μM was achieved. The effect of various potential interfering anions on the perrhenate sensor was also investigated and an excellent selectivity over SCN-, I-, NO3-, NO2-, CO32-, SO42-, MoO42-, WO42- and CH3COO- ions was also achieved. This enabled quantitative measurements of rhenium in some mineral raw samples and the data was also validated by comparing with inductively coupled plasma atomic emission spectroscopy.

“…Such studies demonstrate the usefulness of ICP-MS as an alternative to traditional but slower radiometric techniques. The use of high-efficiency cones and desolvating nebulisers allowed the 143 Nd/ 144 Nd ratio to be determined on trace levels (1-5 ng) of Nd. 113 Used in conjunction with a high-yield column preconcentration step, the long term measurement precision of the 143 Nd/ 144 Nd ratio was (AE0.000016, 2 SD), comparable to that of TIMS analysis.…”

This is the 29th annual review of the application of atomic spectrometry to the chemical analysis of environmental samples. This Update refers to papers published approximately between September 2012 and July 2013 and continues the series of Atomic Spectrometry Updates (ASUs) in Environmental Analysis 1 that should be read in conjunction with other related ASUs in the series namely: clinical and biological materials, foods and beverages; 2 advances in atomic spectrometry and related techniques; 3 elemental speciation; 3 X-ray spectrometry 4 and advances in the analysis of metals, chemicals and materials. 5 In the field of air analysis, highlights within this review period include measuring the bioaccessible fraction of metals in particles and ongoing work in assessing the performance of optical and combustion techniques for the determination of the carbonaceous content of airborne

“…Химическая подготовка проб является наиболее сложным и длительным этапом серийных анализов с использованием инструментальных методов аналитического контроля и предусматривает перевод анализируемого объекта в раствор одним из способов: кислотное разложение, спекание, сплавление, электрохимическое растворение и т.д. При этом рений переходит в раствор в виде перренат-ионов, но на этом этапе возможны его потери в виде летучих оксидов, галогенидов и оксигалогенидов [1].…”

Cr и Fe) в кристаллическом состоянии: стандартная энтальпия образования (ΔH°2 98), стандартная энтропия (S°2 98) и температурная зависимость теплоемкости (С р (Т)) в диапазоне температур 298.15-1200 K. Методы, основанные на методе групповых составляющих, были использованы для оценки ΔH°2 98 (эмпирический метод Ле Вана, инкрементный метод и метод Мостафа) и S°2 98 (инкрементный метод Кумока и правило Неймана-Коппа). Для расчета коэффициентов a, b, c в уравнении C p = а + 0.001•b•T + 10 5 •c•T-2 были использованы аддитивный метод, эмпирические формулы Абашидзе и Цагарейшвили и метод Мостафа. Значения величин, полученные различными методами, были усреднены и использованы в термодинамическом моделировании. С использованием программного комплекса HSC 6.1, дополненного рассчитанными и усредненными термодинамическими свойствами перренатов металлов, выполнено термодинамическое моделирование процесса спекания ренийсодержащих материалов. Рассмотрено спекание проб, содержащих рений, с оксидом магния в отсутствии и присутствии окислительной добавки (NaNO 3 или K 2 S 2 O 7). Показано, что добавление окислительной добавки приводит к минимизации газообразных потерь рения в процессе спекания. Полученные теоретические результаты согласуются с экспериментальными, что говорит о применимости рассчитанных нами термодинамических свойств перренатов металлов. Рассчитанные термодинамические свойства перренатов металлов могут быть использованы для различных термодинамических расчетов как в аналитической химии, так и в металлургии.
