Electrochemical detection of As(III) ions in hot spring water based on a SiO2-Au nanocomposite

Abstract

I In this report, a SiO2-Au nanohybrid was prepared for the detection of As(III) ions using an electrochemical strategy. The morphology and properties of the SiO2-Au nanohybrid were characterized and analyzed via multiple techniques. Under optimized conditions, this nanohybrid material was utilized in the detection of As(III) in hot spring water samples collected from a tourist destination. The results suggested that an electrochemical sensor for the detection of As(III) could be used as a tool for the environmental protection of this tourist destination.
