En el presente trabajo se evaluó de la capacidad de adsorción de una mezcla de quitosano (Ch) y poli-épsilon-caprolactona (PCL) como matriz para la remoción de cobre en aguas residuales utilizando aguas modelo, para ello se caracterizaron 3 tipos de quitinas desacetiladas a tres tiempos (1, 2 y 3.5 h),...
In this work, chitosan cross-linked cellulose fibers were prepared using non-toxic and eco-friendly procedures in order to confer antimicrobial properties to cellulose fibers. Initially, commercial chitosans and chitooligosaccharides were physico-chemically characterized and the latter were tested by assays in vitro. Chitosan was selected based on molecular weight and acetylation degree....
Currently, there is a growing interest in sustainable polymers particularly in basic applications such as packaging, edible films and coatings which biodegrade under controlled conditions of storage in order to alleviate the growing global synthetic materials waste problem. In this regard, the chitosan and its derivatives have demonstrated great potential...
