“…Shuto et al (2006) published new REE data for W-2 and BIR-1. Tiwari et al (2006) developed a highly sensitive method for the determination of Sb and showed new data for AGV-1. Precision and accuracy of ICP-AES and ICP-MS results were evaluated using G-2, AGV-1 and GSR-3 (She et al 2006).…”

This review surveys the literature on reference materials for geological and environmental research for the two year period 2006–2007. In this time ca. 1200 publications appeared containing analytical data on reference materials, indicating that their importance for analytical work has been recognised by geochemists and environmental scientists. Although many reference materials exist, there remains a pressing need for further samples, especially for certified rock reference materials, homogeneous reference glasses, mineral reference materials and so‐called delta‐zero materials for normalisation purposes of stable isotopes. This review focuses on six topics: rock reference materials, reference materials for platinum‐group elements, reference glasses, mineral reference materials, environmental reference materials (seawater, soil) and isotopic reference materials (radiogenic, stable isotopes). In addition, a short description is given of the GeoReM database for reference materials of geological and environmental interest, which contains analytical data from the publications discussed in this review.

The aim of this research was to develop a new sensitive and simple spectrophotometric method for the determination of sodium 2 sulfanylethanesulfonate (SSES) with leucocrystal violet. The procedure is based on a redox reaction occurring between the SSES and potassium iodate in an acidic medium. Formed in stoichiometric quantity iodine oxidizes leucocrystal violet to the crystal violet dye, whose coloring is a base of the spectrophotometric measurements. The crystal violet dye formed shows maximum and stable absor bance at pH = 4.1 ± 0.1 and λ = 590 nm. The molar absorptivity, limit of detection and limit of determination of the method were calculated to be 6.98 × 10 4 L/mol cm, 0.10 and 0.13 μg/mL, respectively. The color system obeys Beer's law in the range 0.2-2.0 μg/mL of SSES. The optimum analytical conditions were evaluated. The proposed method has been successfully applied to the determination of SSES in pharmaceutical prepa rations, without the need of any complicated instrumentation. Reliability of determination was confirmed applying standard iodometric method, recommended by European and Polish Pharmacopoeia.

“…A espectrofotometria é uma técnica simples, rápida e versátil para a determinação de substâncias. Reagentes como, leucocristal de violeta (Tiwari et al, 2006) e vermelho de bromopirogalol (Rath et al, 1997) foram relatados para a determinação de quantidades traço de antimônio. Os métodos são sensíveis, mas têm baixa seletividade, reprodutibilidade e são aplicáveis apenas a amostras específicas (Tiwari et al, 2006).…”
