A quitosana e suas aplicações: uma análise exploratória de dados bibliográficos

Abstract

This paper is an exploratory study, carried out through a systematic review of the literature in the databases Scielo, Google Academic and Science Direct, aiming to make a bibliographical research about chitosan and its applications and, in addition, to identify an application of this polymer or one of its derivatives in the oil industry. It was concluded that chitosan and its derivatives are becoming very attractive for a wide variety of applications in many fields. Its interaction with metal ions by the chelation mechanism allows chitosan derivatives to be an alternative to traditional water treatment processes. In the medical and pharmaceutical field, chitosan derivatives can be applied as analgesics to animals, wound healing improvers and devices for the controlled release of drugs. In the food and agriculture sector, chitosan derivatives can be applied to the preservation of food, packaging material for the conservation of these and increasing the shelf-life of fruits in the post-harvest. In the oil industry, studies have shown that carboxymethylchitosan can effectively be applied as a calcium carbonate scale inhibitor.
