Uriel Fernando Carreño Sayago This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-6457256/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract Bacterial cellulose (BC) is a polymer composed entirely of cellulose. This characteristic confers upon it a multitude of active sites that can be exchanged for heavy metals present in polluting effluents, thus offering a potential solution to the environmental problem of industrial pollutants in water bodies. This is of particular pertinence given the well-documented deleterious effects of heavy metals on aquatic ecosystems. In this context, the objective of determining thermodynamic models in Cr(VI) adsorption processes in BC is proposed. The characterization of bacterial cellulose was undertaken to establish the initial conditions of the process, which led it to initiate Cr(VI) adsorption processes at different concentrations and temperatures. In this study, isothermal models were evaluated, together with batch adsorption kinetics. The findings of this study demonstrate that bacterial cellulose biomass holds great promise for Cr(VI) removal at a variety of temperatures, showing optimal adsorption efficiency at higher temperatures with an adsorption capacity of 140 mg/g and a similarly significant reduction of 125 mg/g in the removal of this heavy metal at lower temperatures. The utilization of this biomaterial in an environmental sustainability initiative focused on water resource protection is a highly promising prospect.
