In the present study, Morchella esculenta mushroom, a low cost biosorbent, was investigated for the adsorption of EBT dye. The biosorbent was characterized using Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX). Parameters such as solution equilibrium pH, biosorbent dosage, isotherm, kinetics, thermodynamics, desorption and reusability were investigated. Langmuir, Freundlich, Temkin Dubinin–Radushkevich (D–R) isotherm and Scatchard isotherm models were used to understand the reaction kinetics and the reaction was found to be spontaneously endothermic. In this study, four different kinetic models were investigated, namely pseudo first order (PFO), pseudo second order (PSO), intraparticle diffusion (IPD) and Elovich. Maximum adsorption was observed as 88 % at pH 5.0. An increase in dye adsorption efficiency was observed with increasing adsorbent amount. The highest desorption of EBT occurred under basic conditions. It was found that after regeneration of Morchella esculenta, it could be reused for at least four cycles to remove EBT from aqueous solutions. It was determined that the proposed biosorption process could effectively remove EBT from various aqueous media and could be used in industrial processes. A molecular dynamics (MD) simulation was performed to evaluate the behavior of EBT in the system containing Morchella esculenta components. The MD results revealed this azo dye can effectively interact with the biosorbent components. Lastly, the best molecules are calculated by Gaussian software for the electrostatic potential map and active region.
