Glyphosate [N-(phosphonomethyl)-glycine] is a herbicide with several commercial formulations that are used generally in agriculture for the control of various weeds. It is the most used pesticide in the world and comprises multiple constituents (coadjutants, salts, and others) that help to effectively reach the action’s mechanism in plants. Due to its extensive and inadequate use, this herbicide has been frequently detected in water, principally in surface and groundwater nearest to agricultural areas. Its presence in the aquatic environment poses chronic and remote hazards to human health and the environment. Therefore, it becomes necessary to develop treatment processes to remediate aquatic environments polluted with glyphosate, its metabolites, and/or coadjutants. This review is focused on conventional and non-conventional water treatment processes developed for water polluted with glyphosate herbicide; it describes the fundamental mechanism of water treatment processes and their applications are summarized. It addressed biological processes (bacterial and fungi degradation), physicochemical processes (adsorption, membrane filtration), advanced oxidation processes—AOPs (photocatalysis, electrochemical oxidation, photo-electrocatalysis, among others) and combined water treatment processes. Finally, the main operating parameters and the effectiveness of treatment processes are analyzed, ending with an analysis of the challenges in this field of research.

草甘膦污染水处理技术：综述


草甘膦 [N-(膦酰甲基)-甘氨酸] 是一种除草剂，具有多种商业配方，通常在农业中用于控制各种杂草。它是世界上使用最广泛的农药，包含多种成分（助剂、盐等），有助于有效地在植物中发挥作用机制。由于其广泛且不充分的使用，这种除草剂经常在水中检测到，主要是在最靠近农业区的地表水和地下水中。它在水生环境中的存在对人类健康和环境造成长期和远程危害。因此，有必要开发处理方法来修复被草甘膦、其代谢物和/或助剂污染的水生环境。本次审查的重点是针对草甘膦除草剂污染的水开发的常规和非常规水处理工艺；它描述了水处理过程的基本机理并总结了它们的应用。它涉及生物过程（细菌和真菌降解）、物理化学过程（吸附、膜过滤）、高级氧化过程——AOP（光催化、电化学氧化、光电催化等）和组合水处理过程。最后，分析了主要操作参数和处理过程的有效性，并分析了该研究领域的挑战。
