Improved anodic stripping voltammetric detection of zinc on a disposable screen-printed gold electrode
Herein, we report the improved detection of Zn 2+ via square-wave anodic stripping voltammetry utilizing an electrochemically treated screen-printed gold electrode. Surface analysis of the gold surface revealed increase in rugosity, removal of residual polymeric ink, and consequent higher access to...

Britton-Robinson buffer (pH 7.0) as the background electrolyte. Satisfactory recovery values ranging 96 to 104% were achieved for the analysis of struvite (spiked sample). Therefore, the proposed sensor provides precise and accurate direct analyses, without interference from other metals, with rapid responses enabling on-site analyses.
