摘要

•A rapid voltammetric method for monitoring of trace Αs(III) was developed.•Disposable injection-moulded sensors are used in a portable configuration.•Detection is performed at an in-situ electroplated gold film electrode.•A sub-μg L-1 limit of detection is achieved for As(III)•The interference by Cu(II) is alleviated using potassium ferrocyanide.
