摘要: Hexavalent chromium (Cr (VI)) has strong oxidizing properties and can result in carcinogenic effects on human bodies. Therefore, it is necessary to detect hexavalent sensitively accurately. This article proposes the gold nanoparticles (AuNPs)–boron-doped diamond (BDD) electrode for direct determination of with a green simple detection process by cathodic stripping voltammetry. Gold are used enhance performance toward Cr (VI). The effect different pretreatment methods modification been studied, parameters have optimized. With optimized conditions, AuNPs–BDD presents good linear behavior (VI) concentration range 10 1000 μg/L. A low limit 1.19 μg/L achieved. environmentally friendly. sensor tested real water sample satisfactory results, which indicates potential application sensitive onsite
