Adsorption isotherms and kinetics were applied at 10, 25, and 35 degrees C. The adsorption of methylene violet 2B and basic yellow 28 on the black cumin seed pulp and biochar surface was exothermic; the heat of adsorption values were lower CC were 212.8, 625, 164, and 909 mg g-1 at 25 degrees C, respectively. The adsorption of black cumin seed pulp and biochar data were examined with Flory-Huggins (F-H) isotherm models. The kinetics of the adsorption were fitted to the pseudo first-order and pseudo second order equations. The pseudo second order equation gave a better fit than the pseudo first-order equation.eninfo:eu-repo/semantics/openAccessBlack cumin seed pulpBiocharBY28MVAdsorptionArticle10.15376/biores.18.2.3414-34392-s2.0-8515293974234392Q3341418WOS:000967659000003Q2
