Abstract

Electrochemical stripping analysis (ECSA) is a promising method for metal ions detection. However, the low sensitivity and poor reproducibility limits its practical applications. The combination with other powerful detection techniques to address these concerns is highly desirable. Herein, the anodic stripping method and photoelectrochemical (PEC) technique are integrated into a new detection platform of PEC stripping analysis (PECSA) with bismuth vanadate (BiVO4) as both optoelectronic material and an electrochemical enrichment candidate. The new PECSA strategy presents high sensitivity and excellent reproducibility; in addition, inherited from the ECSA, this strategy also offers new selectivity dimensions through the potential-dependent response and thus implements reproducible, sensitive, and selective detection of silver ion (Ag+) in real biological and environmental samples. The success of PECAS strategy shed light on the rational combination of various analysis techniques for versatile applications.
