The physical-chemical adsorption of Rhodamine B (RhB) dye for the different materials is studied in detail, together with the thermodynamic feasibility and the spontaneous and endothermic nature of the biosorption process. Subsequently, the production of total reducing sugars (TRS) is compared by enzymatic hydrolysis (before and after the adsorption process of the RhB pollutant), confirming the viability of TRS production in all cases, with yields ranging from 65.9% for pine nut shell (after adsorption) to 74.9% for the carnauba endocarp and to 84.0% for carnauba leaves (before adsorption). Hence the use of lignocellulosic materials as adsorbents does not preclude their ulterior reuse for obtaining fermentable sugars by enzymatic hydrolysis. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.764 2017 MATERIALS SCIENCE, PAPER & WOOD 11 / 21 = 0.524 2017 Q3 T2 0.303 2017 Organic Chemistry 2017 Q3 Materials Chemistry 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion López Sotelo, Juan Benito Correa Guimaraes, Adriana Hernández Navarro, Salvador Sánchez Báscones, Mercedes Navas Gracia, Luis Manuel (orcid)0000-0003-2713-2786 Martín Ramos, Pablo Universidad de Zaragoza Martín Gil, Jesús 5011 500 Universidad de Zaragoza Dpto.
