Batch adsorption of methylene blue dye using Enterolobium contortisiliquum as bioadsorbent: Experimental, mathematical modeling and simulation

Abstract Discoloration of cationic dyes in effluents is essential to reduce the impacts caused to the fluvial ecosystem. In this work, the adsorption of methylene blue was studied using Enterolobium contortisiliquum as bioadsorbent. The bioadsorbent showed structural and superficial potentiality in the process. The Langmuir model adjusted the experimental equilibrium data, presenting R² and R²adj > 0.98 and EMR
