Production of hydrogels for the removal of water residues based on cellulose extracted from fruit residue

Abstract

This article analyzes the conceptual framework in specialized literature on the manufacture of fruit-based hydrogel through which the environmental impact is reduced; In addition, due to its three-dimensional structure and flexibility, it can be manufactured through physical or chemical crosslinking. Their rubberiness is an advantage that allows them to resemble the tissues of living beings; and due to its easy adaptation to these and to cellulose, which is a natural polymer and abundant in nature, its use is constantly increasing in industry and in optometry; It is also produced in plants and bacteria by means of chemical dissolution. It is also stated that the industry, due to its dyes, pollutes surface water reserves and groundwater; and the use of hydrogels have contributed to reducing said contamination thanks to their absorption; and they are also used, successfully, for the cleaning of dyes in waste water. The methodology used consisted of the review of around eight bibliographic sources in which more than forty researchers participated; Next, the method of extracting cellulose and elaborating hydrogels is briefly described, based on which the conclusions are reached that cellulose-based hydrogels have the property of absorbing and retaining a large amount of water that provides them with various physicochemical properties that make hydrogels have a wide range of applications of interest for industry, as well as for science, in general, and in biomedicine for the manufacture of contact lenses and the removal of dyes from water
