SUMMARY:

Human actions have affected the quality of water resources causing great impact to the environment around the world, significantly reducing their availability for consumption. Faced with the priority need to remove contaminants and pollutants in the most diverse aquatic matrices, the development of new technologies for this purpose becomes essential. Some decontamination processes employ solid materials for adsorption, providing low cost associated with high efficiency. The lamellar double hydroxides (HDLs) in addition to being versatile, show promise in adsorption processes. A Scoping Review was carried out in order to obtain a global overview of what has been studied on the use of lamellar double hydroxides as adsorbing agents for contaminants and pollutants in aquatic matrices. Data collection was performed by searching publications by three independent reviewers on online platforms (a) Web of Science (WoS); (b) Scopus; (c) Science Direct; (d) National Library of Medicine (PubMed), (e) Google Scholar and (f) Open Grey; through the use of keywords: layered double hydroxides, environment, contaminant, pollutant, aqueous medium, aqueous solution, adsorption, adsorbent and adsorbent agent. The inclusion criteria were: publications indexed in selected databases that contribute in a relevant way to the research question and open access. The chronology used was from the date of origin of each electronic platform until the year 2021. Based on the eligibility criteria, 17 studies were selected, from 14 different nationalities, with their publication period between 2005 and 2021, denoting the scientific effort of 103 researchers. The predominance of the origin of the studies was recorded, as well as the composition of the HDLs used, the contaminants, the pollutants or reaction media in which they were used, the synthesis method used and the most relevant considerations of each research. This work evidenced the main information that describes the HDLs as promising materials and of significant relevance as an adsorbent of contaminating agents and pollutants in aquatic matrices, highlighting the challenges identified for the emergence of new studies on the subject.
