The current moment requires the development of new technologies that can provide alternatives to conventional treatment and that efficiently remove pollutants that are difficult to treat. Activated carbon has been highlighted as low cost material that can be used as adsorbents for the removal of contaminants. Thus, the aim of the present study was to analyse the relevant literature related to the production of activated carbon for the treatment of water. For the study, there were found 4,182 relevant studies in the database of the Web of Science and from these restrictions and readings were obtained 27 articles. The information obtained was: i - temporal evolution of publications, ii - distribution of articles by periodicals, iii - spatial distribution, iv - precursor material, v - activation technology, vi - pollutants and vii - treatment efficiency. Results show that the activated carbon produced from corn and industrial ash residues are good adsorbents. Dyes, heavy metals and phenols were the most studied pollutants, and had the higher treatment efficiency values. The approach of the present study allows to identify the main points of this new technology and it helps to support new researches and applications
