Abstract

This work aims to search for treatment methods for water containing dyes and pigments using the Espacenet and ScienceDirect databases. The methodology consisted in associating the words dye *, pigment *, treatment *, water * and method * finding 296 patents and 25,792 works of scientific dissemination. China, United Kingdom and the United States were the most prominent countries in filing patents on the subject, indicating that such countries are safe in the appropriation of their knowledge. From the analysis of the patents it was verified that the methods for removal of dyes and pigments from water still little explored, having high potential to generate innovation. From the analysis of published scientific papers it was verified that there is a large number of publications related to the topic, and that the original articles are the most publicized form on the subject.
