摘要：
A sensitive, simple, fast, and inexpensive method for determining diuron in water using square wave voltammetry and a glassy carbon electrode is presented. This method was developed to evaluate diuron contamination in river waters close to sugarcane cultivation, located in the metropolitan region of Joao Pessoa, in the state of Paraiba, Brazil. An analytical curve with a linear response ranging from 38.5-115.0 nmol L-1 (r(2) = 0.993), a LOD equal 0.2 nmol L-1, and recovery rates from 88.0 to 108.0 %. The proposed method does not require any previous chemical treatment of the sample, thus contributing to green analytical chemistry.
