TL;DR: In this paper, the solutions of single real formulations of herbicides tebuthiuron and ametryn have been degraded by anodic oxidation with electrogenerated H2O2, electro-Fenton (EF), and solar photoelectro-fenton (SPEF), in a flow plant of 2.5 L equipped with a boron-doped diamond (BDD)/air-diffusion cell and a solar planar photoreactor.

TL;DR: In this paper, a new electroanalytical procedure was developed for the determination of lidocaine in commercial local anesthetics products containing lidocaine as the active ingredient, based on the use of electrochemical methods as cyclic and square wave voltammetry, with boron-doped diamond electrodes.

TL;DR: In this article, the degradation of chlorimuron-ethyl, which belongs to the class of sulfonylurea herbicide, was performed by Fenton, photo-Fenton and ozonation.

TL;DR: The PEF process was the most powerful since it led to total mineralization by the combined oxidative action of hydroxyl radicals and UVA irradiation, and the EO-H2O2 process had the lowest oxidation ability due to the slow reaction of intermediates with •OH produced from water discharge at the BDD anode.

TL;DR: A safe water supply and appropriate sanitation are the most essential components for a healthy and prosperous life as mentioned in this paper, however, increases in human activities have led to exposure of the aqueous environment to chemical, microbial and biological pollutants as well as to micropollutants.
