Screen-Printed Electrodes for the Voltammetric Sensing of Benzotriazoles in Water

Benzotriazoles (BZTs) are high production volume industrial chemicals that are used in various applications such as corrosion inhibitors, antifreeze agents, and UV radiation stabilizers. Given their potential ecotoxicological implications for different ecosystems and in human health, as well as thei...
