Sample digestion methods for the determination of traces of precious metals by spectrometric techniques.
Recent advances in digestion methods used in the analysis of precious metal samples by spectrometric techniques are reviewed. The applicability of a fire assay, a wet acid treatment, chlorination and alkaline oxidizing fusion to a quantitative recovery of metals from various materials is discussed. Data on the precious metal contents obtained by using particular digestion methods as well as UV-...
متن کاملPotential Health Risk Assessment of Different Heavy Metals in Wheat Products
In the present work, health risk of heavy metals such as As, Cd, Co, Cr, Cu, Hg, Ni, Pb, Zn in Iranian urban and rural samples including wheat, wheat flour, bread, pasta and sweets were assessed. The real amount of heavy metals in target samples were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and atomic absorption spectroscopy (AAS). Wet ashing and hydride g...

متن کاملEvaluation of two different extraction techniques on determination of 〖Pb〗^(+2) contents of wastes of dye manufacturing industries
Extraction of trace amounts of toxic heavy metals from complicated environmental matrixes is a challenging task. The aim of this investigation is the comparison of the extraction efficiencies and other related experimental variables ( chemicals, effect of pH, potential interfering ions) on the determination of inorganic lead ( ) which is present in waste water of dye industries. Compared techn...
متن کاملReview of preconcentration and solid phase extraction for the determination of trace Lead
Spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. The use of an appropriate sample handling technique is a...
