Calendula officinalis is a low-cost material used as adsorbent for the removal of textile dye, Brown HE-2G.  The effect of pH, concentration of dyes, adsorbent dose and contact time were obtained by batch adsorption technique.  The results were analyzed by adsorption isotherm models (Freundlich, Langmuir, Redlich-Peterson and Tempkin).  The results were in good agreement with Langmuir model and the Redlich-Peterson isotherm models.  The Langmuir monolayer adsorption quantity was found to be, 76.56 mg g-1 Brown HE-2G.  Pseudo-first-order, pseudo-second-order, Intraparticle diffusion and Tempkin kinetic models were used to fit the experimental data, it was well fitted into pseudo second order kinetics. FT-IR and SEM analysis have effectively supported the adsorption of Brown HE2G on the adsorbent.
