Summary: Salicylaldehyde functionalized chitosan (S-CHIT) was successfully synthesized and attached to the surface of acetylene black paste electrode (ABPE) to construct an electrochemical sensor. The electrochemical behaviors of catechol (CC) and hydroquinone (HQ) on the S-CHIT/ABPE were investigated using cyclic voltammetry (CV) and second-order derivative linear sweep voltammetry (SDLSV). Quantitative determination of CC and HQ was achieved using SDLSV with the oxidation signal. The results demonstrate that S-CHIT/ABPE is a promising electrochemical sensor for the simultaneous detection of CC and HQ.

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.
