PRODUCTION OF MICROBIAL CELLULOSE FROM AMAZON AA WASTE FOR THE REMOVAL OF Cu (II) IN INDUSTRIAL EFFLUENTS

Abstract

Currently, the most used adsorbent is activated carbon. However, its application can be expensive. One technique that may be economically viable is biosorption, which uses biomass (biosorbent) to remove pollutants. From this perspective, the main objective of this research was to develop an adsorbent material consisting of Microbial Cellulose (CM), analyzing the feasibility of using waste from aa production to remove copper ions present in synthetic effluents. Initially, preliminary tests were carried out on the feasibility of production and possible adsorption, including a predictive molecular coupling simulation; then, tests of the influence of temperature on the cultivation of CM (20C, 30C, 40C) were carried out, kinetic tests were carried out to define the adsorption models, varying:Humid Base (HB); Dry Base (DB); granulated, mass ratio MCM/Mcu+2 (20, 35, 50) and pH (2, 4, 6) in biosorption. Characterizations were performed using Fourier transform infrared spectroscopy (FTIR) and ethanol infiltration method (Porosity). In all kinetic runs, it was possible to obtain a percentage of removal, in addition, it was evidenced that the optimal parameter of cultivation is at 30C, obtaining a considerable amount of mass and porosity, in addition, the structural form of economically viable use was defined HB and pH 2 in the adsorption solution, obtaining a copper ion removal performance of 64.95%, whose experimental data were better adjusted to the Elovich model. With the results found in this research, , it can be stated that the CM presents appropriate characteristics for the copper adsorption process and that it can be an alternative to classic effluent treatment processes.
