determination of fluorine by total reflection x-ray

Determination of residual metal concentration in

Total reflection X‐ray fluorescence spectrometry (TXRF) was used to determine residual metal content in metallurgical slag after sulfuric acid extraction. A slag sample provided by a copper smelter industry and submitted to a recycling process with the aim of extracting valuable metals was analyzed. Slurry sampling was evaluated as a simple sample preparation procedure for the determination

Determination of Mercury(II) in Drinking Water by Total

The total reflection X-ray fluorescence determination of mercury(II) in drinking water at concentrations of 7 10 −2 to 3.0 g/L is reported. The mercury(II) preconcentration protocol includes directly suspended droplet microextraction with benzene as a molecular iodine complex.

Determination of Halide Ions in Solution by Total

An accurate quantitative determination of halide ions X (X = Cl, Br, I) in aqueous solution by total reflection X-ray fluorescence (TXRF) is not possible using the traditional acidic internal standards. In general, the standard solutions are highly acidic (e.g., Ga(NO 3) 3 in HNO 3) to avoid precipitation of hydroxides of the standard element and to obtain a stable and reliable standard.

Determination of fluorine by total reflection X

Total reflection X-ray fluorescence spectrometry (TXRF) is known as a state-of-the-art and fast-growing analytical technique. The spectral range of TXRF spectrometry encompasses elements from sodium to uranium. The object of this study was to develop, optimize, and validate the analytical method for fluorine in a form of calcium fluoride determination in fluoride fluxes by total reflection X

Analytical possibilities of total reflection X

However, its determination is challenging due to low concentrations within complex matrices that hamper the analysis in most spectroscopic techniques. In this study, we explored the possibilities of several analytical approaches combined with total reflection X-ray (TXRF) spectrometry for soil Se determinations.

Determination of fluorine by total reflection X

2010/4/1There is a growing interest in determination of low Z elements, i.e. carbon to phosphorus, in various samples. Total reflection X-ray fluorescence spectrometry (TXRF) has been already established as a suitable trace element analytical method with low sample demand and quite good quantification limits. Recently, the determinable element range was extended towards Z = 6 (carbon). In this study

Determination of arsenic in water samples by Total

The determination of arsenic in water samples requires techniques of high sensitivity. Total Reflection X-Ray Fluorescence (TXRF) allows the determination but a prior separation and pre-concentration procedure is necessary. Alumina is a suitable substrate for the selective separation of the analytes. A method for separation and pre-concentration in alumina, followed by direct analysis of the
