In this population driven society, the major causes of environmental pollution are modern agricultural practices and intensified industrialization. These kind of economic practices lead to excessive deposition of residual pesticides and heavy metals in both soil and water. Due to their quicker advancement in in-situ and point-of-care technologies, electrochemical sensing methods have chosen as best for detecting these contaminants. ‘Graphene’, a wonder material possessing excellent physiochemical properties when utilized as an electrode for sensing, enables quicker diffusion of target analytes. Graphene-based nanocomposites, when used as a working electrodes, allow for detection of environmental contaminants even at trace levels. Presently, scientists are working to develop an electrochemical sensor which facilitates accuracy and high sensitivity. This review highlights the performance of graphene composites in detecting various environmental pollutants using electrochemical sensing strategies. Further, comparative study on its methods and techniques, existing problems with some solutions and future aspects are briefly discussed.

Fenuron (FEN) is a herbicide that acts as a weed growing inhibitor in crops. Due to its persistence and good solubility in water, its presence in water bodies is emerging as a concern for aquatic species. Herein, we propose a simple development of an electrochemically reduced graphene oxide (rGO) sensor for the monitoring of FEN in water samples. The electrochemical determination of FEN showed the best performance in a 0.1 mol L − 1 NaCl solution (pH = 2.5). Differential pulse voltammetry (DPV) was performed using optimal parameters and resulted in two linear ranges (0.4-12 µmol L − 1 and 20 to 50 µmol L − 1 ) with high sensitivities of 6.83 and 1.9 µA µmol − 1 L, respectively, and a low LD of 0.34 µmol L − 1 . Stability, reproducibility, and interference tests showed that rGO is su ciently reliable to be used as a sensor of FEN in real samples. Spiked tap and canal water samples returned recoveries close to 100%, exhibiting no statistically signi cant difference when compared to a UV-Vis method by an average paired t-test, attesting the viability of the rGO modi ed electrode as a promising sensor of FEN in environmental water samples.
