“…Chromium emission line 357.869 nm could have significant interference from cobalt emission lines 357.890 nm and 357.903 nm in the case of samples with high cobalt concentration levels. 24 Thus, spectral line 283.563 nm was adopted for chromium quantification, although 357.890 nm provided higher sensitivity. Peak height measurements of the emission intensity transient signal and external calibration with aqueous standard solutions were used for quantification.…”

This work covers an investigation into the potential of developing an automated on-line column preconcentration system using the readily available micro-cartridge HyperSep SCX for fast simultaneous determination of trace Ag(I), Cd(II), Co(II), Cr(III), Cu(II), Fe(III), Mn(II), Ni(II), Pb(II) and Zn(II) ions by inductively coupled plasma atomic emission spectrometry. The proposed method was based on the quantitative sorption of target elements onto the surface of the strong cation exchange resin at pH $2.0, and complete elution with 2.0 mol L À1 HCl. All factors affecting the performance of the system such as sample acidity, loading and elution flow rate, preconcentration time as well as radio frequency (RF) incident power and nebulizer gas flow rate were examined in detail. The noticeable reduced consumption of chemicals along with automatic manipulations enabled the realization of a simplified and relatively clean procedure with low detection limits in the range of 0.05 and 0.2 mg L À1 . Under the optimal conditions, the developed method provided a sampling frequency of 24 h À1 for all 10 studied elements. The accuracy of the developed method was evaluated by analyzing certified reference materials and spiked environmental natural water samples.

“…In both cases, any liquid-based analytical methods require time-consuming decomposition procedures, the use of which is frequently associated with the risk of incomplete sample dissolution or loss of some of the elements. The decomposition is usually performed by means of a mixture of acids [1] or by using a solution of 5% aqua regia in 30% hydrogen peroxide [2].…”

“…3 Grain growth is undesirable because it may weaken the product, especially in the manufacture of cutting tools. 2 Used materials are also recycled 4 and the composition of these is of importance in deciding the most suitable use of the material. In a powder metallurgy research environment, the concentrations of these metals must be accurately known to predict the physical properties of the finished product.…”

SYNOPSISInductively coupled plasma-optical emission spectroscopy was used to measure the concentrations of cobalt, tantalum, titanium, vanadium and chromium in solutions of tungsten carbide. The main advantage of the method described here lies in the speed, convenience and effectiveness of the dissolution procedure. Aliquots ofpowdered tungsten carbide are dissolved in 5% aqua regia in 30% hydrogen peroxide. Complete dissolution was usually achieved within 10 minutes. The accuracy and precision of this novel method was assessed by the analysis of certified reference materials, secondary reference materials and matrix spiking. The method was successfully applied to commercial type samples with differing compositions. SAMEVATTINGInduktief gekoppeIde plasma-optiese emissie spektrometrie is gebruik om die konsentrasie van kobalt, tantaal, titaan, vanadium en chroom in oplossings van wolframkarbied te bepaal. Die hoofvoordeel van die metode wat hier beskryf word, is die spoed, gemak en doeltreffendheid van die monster voorbereiding. Verpoeierde wolframkarbied monsters het gewoonlik binne 10 minute opgelos na die byvoeging van 'n mengsel bestaande uit 5% aqua regia in 30% waterstofperoksied. Die akkuraatheid en presisie van hierdie nuwe metode is ondersoek deur gesertifiseerde verwysingsmateriale en sekondere verwysingsmateriale te ontleed, asook deur matrysbyvoegings. Die metode is suksesvol toegepas op kommersieele monsters met verskillende samestellings.
