Production of biossorvente magnetized base type polysaccharide biopolymers, for removal of chromium (VI) from industrial effluents

摘要

Production of biossorvente magnetized base type polysaccharide biopolymers, for removal of chromium (VI) from industrial effluents.The present invention relates to the development of a new biossorvente with fibres of Cocos nucifera, from agro industrial waste, superparamagnetic behavior.Through the incorporation of nanoparticles of magnetite for processes for the remediation of chromium (VI) from industrial effluents, as an alternative, technologically and economically feasible.Without the generation of secondary waste.The production process of this new biossorvente, involves: (1) preparation of the reaction medium with the waste fibers of Cocos nucifera, both in the form of fibre, how powder,The solution of iron (III) chloride hexahydrate and ferrous chloride solution II tetrahydrate, with heating to 70 u00b0 C for 30 minutes; (2) the addition of NaOH to pH 11; (3) heating at 70 u00b0 C,For 30 minutes; (4) gradual cooling to room temperature (27 + or - 2 u00b0 C); (5) drying at 80 u00b5 m Hg for 90 minutes (Route 1)Or drying in the oven 75 u00b0 C for 2 hours (Route 2) or natural drying for four days at room temperature (route 3); (6) washing with distilled water until the pH neutralization and drying temperature ambieNTE. It is expected, therefore, to reduce environmental problems.
