The presence of contaminants in the water is a problem that worries humanity since the consumption of water with inadequate concentrations of contaminants can cause serious problems to human health, and different technologies have been used to reduce or eliminate those contaminants in drinking water. Adsorption has been highlighted because of its low cost and simplicity removal process and, graphene oxide has been reported as excellent adsorbent because it has functional groups that offer stability, antifouling, and hydrophilicity, important to contaminants removal from water. The review of literature related to graphene oxide, water contaminants, and their impact on human health was the basis for the execution of the present work. A thorough analysis of each selected article and critical analysis were made to report the ability to remove contaminants and factors that can contribute positively or negatively to the contaminants removal process. A total of 204 articles were selected, mostly published in the last 5 years, because advances in the use of graphene oxide as adsorbent are reported annually. This article will help to understand better that graphene oxide alone or combined can treat different contaminants from drinking water.
