A rapid, simple technique combining disk solid-phase extraction and handheld X-ray fluorescence (XRF) spectrometry was developed for the on-site determination of As, Se, and Cr(VI) in drinking water. For the pre-concentration of As, Se, and Cr(VI), a 50 mL aqueous sample was adjusted to pH 4, followed by passage through a Ti-loaded anion-exchange disk (Ti-AED). Both sides of the Ti-AED were coated with an adhesive cellophane tape prior to drying using a cordless hair iron, followed by handheld XRF measurement. The Ti-AED adsorbed As(III), As(V), Se(IV), Se(VI), and Cr(VI) in water without requiring oxidation and reduction. The detection limits of As, Se, and Cr(VI) were all 1.0 g L 1 . Good recoveries were obtained by measuring certified reference materials, and spiking natural mineral water with As, Se, and Cr(VI). As the proposed method does not require power supply or toxic reagents in any analytical step, it is suitable for the on-site determination of toxic elements in drinking water.

Abstract. Chemical vapour generation by reduction with sodium tetraborohydride and coupled to inductively coupled plasma spectrometry (HG-ICP-AES) was examined for tin analysis in high-content calcium matrix samples. Comparison of calibration curves in aqueous and matrix-matched solution showed good linearity (R 2 = 0.9951 -0.9999) in the observed range of concentration. The effects of added calcium were established as attenuation of emission intensity for 3 % at 224.605 nm and 235.484 nm and only 1 % at 283.999 nm and 189.991 nm of tin lines. The best limit of detection, i.e. 1.9 mg L -1 in aqueous and 2.1 mg L -1 in matrix-matched solution were obtained at 189.991 nm. Method of standard addition was applied for the analysis of laboratory samples of high purity calcite and aragonite shell structures and it gave 0.11 µg g -1 and 0.17 µg g -1 of tin, respectively. The accuracy of method was tested by certified reference material (NRCC, MESS-3) and good recoveries (100.08 %) were obtained in both calibration modes. Tin content was determined by HG-ICP-AES method using matrix-matched calibration in shell samples of Mytilus galloprovinciallis. The obtained values of tin content showed relatively flat distribution in shells along the coast (0.511 -0.718 µg g -1 ). Higher concentrations were measured on several hotspots, especially fishing ports and harbours. (doi: 10.5562/cca2259)

“…Therefore, developing effective analytical methods for the sensitive detection of trace amounts of Hg 2+ is an increasing demand, and is especially important. 2 Up to now, considerable efforts have been devoted to develop methods for detecting Hg 2+ based on different analytical techniques, such as inductively coupled plasma atomic emission spectrometry, 3 atomic absorption spectrometry 4 and surfaceenhanced Raman scattering. However, these test methods often require complicated sample preparation steps, rigorous experimental conditions, sophisticated instrumentation, and well-trained individuals.…”

9PVA and its related products are good choices for preparing environment-friendly semiconductor nanocomposites due to its wide spectral range of optical transparency, biocompatibility and biodegradability, aiming at detecting environmental samples and biology applications.10 However, the relatively weak bonding ability of hydroxy groups with metal ions has significantly affected its stable conjugation with QDs, which will cause future 2016 © The Japan Society for Analytical Chemistry † To whom correspondence should be addressed. Using environment-friendly materials for sensing toxic metal ions has drawn significant attention in recent research. Herein, we present an aqueous synthesis of stable CdS quantum dots (QDs) using thiol-functionalized poly(vinyl alcohol) (PVA) as the unique capping ligand for the detection of trace Hg 2+ in environmental water samples. The CdS QDs with an average size of 3.3 nm had good water-solubility and favorable fluorescence with a quantum yield of 32.8% and a longer luminescence lifetime of 31.9 ns. The fluorescence intensity of QDs aqueous solution in the 520 nm wavelength was quenched upon the addition of Hg 2+ . Under the optimal conditions, the ratio of the blank fluorescence intensity to the quenched fluorescence intensity was linearly proportional to the Hg 2+ concentration from 2 to 4000 nM with a detection limit of 1 nM. Also, many co-existing metal ions were not interfered with the detection of Hg 2+. This nanomaterial was successfully applied to the measurement of Hg 2+ in water samples.
