Summary: We introduced a novel poly (riboflavin)/carbon black-modified glassy carbon electrode (PRF/CB/GCE) as an electrochemical sensor for simultaneous measurement of Cd2+ and Pb2+ in the presence of bismuth ions, using differential pulse anodic stripping voltammetry (DPASV). The linear range for Cd2+ and Pb2+ was optimized to be 0.5 to 600 nM. The detection limit (LOD) was 0.16 nM for Cd2+ and 0.13 nM for Pb2+. The proposed electrode was successfully applied for simultaneous detection of ions in rice, honey, and vegetable samples, with satisfactory recoveries, demonstrating its practicality for determining Cd2+ and Pb2+. Atomic absorption spectrometry (AAS) was used as a reference technique for detecting ion concentrations in the samples.

Summary: Heavy metal-organic complexes are widespread in contaminated waters and pose a greater challenge for decontamination compared to free ions. Current analytical methods are unable to determine these complexes, impeding the development of decontamination mechanisms. A highly sensitive and selective colorimetric sensor for detecting Cr3+/Hg2+-organic complexes using citrate functionalized silver nanoparticles (Ag NPs) has been developed. The sensor exhibits nanomolar scale detection and its application could greatly advance the instant colorimetric detection of heavy metals in the environment.
