This study investigated the morphological dependence of ZnO nanostructures, specifically nanotube- and nanorod-based electrodes, on their electrochemical performance for detection lead ions (Pb2⁺) in aqueous solutions. The results demonstrate that nanotubes exhibit significantly enhanced sensitivity compared to nanorods during CV measurements. During SWV measurements, (116.79 mA·mM−1) a lower limit 0.0437 μM were determined. hollow, high-aspect-ratio structure provides larger active surface area facilitates better ion accessibility, resulting superior electron transfer efficiency catalytic activity. These underscore critical role morphology optimizing ZnO-based sensors. Analysis real water samples from various natural reservoirs revealed no detectable lead, while was identified exclusively artificially prepared containing exposed hunting shot. Over 30-day period, sensor retained over 95% its initial when stored under vacuum conditions, demonstrating minimal signal degradation. Under ambient stability loss attributed moisture adsorption porous nanostructure. also displayed outstanding reproducibility, with current response variations across multiple probes remaining within 4%. cost-effective simple fabrication process nanostructures further highlights potential scalable production, environmental monitoring, integration into portable sensing devices.

In this study, a novel lignin-based magnetic composite with shell-and-core structure and high saturated strength has been developed for the efficient removal of Pb(II) from wastewater. The adsorbent was fabricated through introduction silica–amino groups cross-linking complex lignin, utilizing Fe-Fe2O3 as source. paramagnetic characteristics enabled its rapid separation aqueous solution within merely 15 s. Batch adsorption experiments demonstrated that adsorbents could reach equilibrium 30 min. When concentration is in low range 0 to 200 mg/L, rate approaches 100%, theoretical maximum capacity 384.2 mg/g. mechanism analysis indicated process primarily characterized monolayer chemisorption. Notably, resultant bio-composites level stability even after eight consecutive desorption cycles, still reaching 82.3%. This work outlines approach designing highly lignin-derived toward wastewater treatment.
