Carbon Paste Electrode Modified With Cuo–Nanoparticles as a Probe for Square Wave Voltammetric Determination of Atrazine

Abstract

Background: Atrazine (ATZ) is a widely used herbicide in most countries because of its low cost and good selectivity. The concentration of ATZ that the EPA considers safe to consume in drinking water is 3 ppb. Therefore, recently, there have been concerns about its determination in trace levels. This compound is not electro-active, so in this research indirect electrochemical method for its detection in low levels was proposed.
