Summary: A practical strategy for detecting trace-level As(III) in natural water without any modifiers using soluble Fe3+ as a trigger is reported. The method achieves an actual detection limit of 1 ppb and a sensitivity of 0.296 mu A ppb(-1) with excellent stability. The codeposition mechanism of Fe3+ preferentially depositing as Fe-0 is confirmed, which facilitates the adsorption of As(III) and H+ on the electrode surface and the formation of AsH3.

Summary: This study proposes a dependable approach for the selective and sensitive identification of zinc, cadmium and lead in different sample matrices using an over-oxidized poly(xylenol blue) film glassy carbon electrode coated with bismuth (Bi/PXBov.ox/GCE). The best conditions for determining these elements were found to be a 0.1 mol L-1 acetate buffer solution as supporting electrolyte (pH 4.5), -1.5 V accumulation potential, and 180 s accumulation duration. Under these conditions, the detection limits of Zn(II), Cd(II) and Pb(II) were 3.20 μg L-1, 0.21 μg L-1 and 1.98 μg L-1, respectively. Moreover, this novel, cheap and easy-to-prepare Bi/PXBov.ox/GCE was successfully used for the analysis of Zn(II), Cd(II) and Pb(II) in lipstick samples, with consistent results compared to inductively coupled plasma mass spectrometry.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
