“…Methyl violet 2B (CAS number: 8004-87-3, molecular weight: 393.95 g/mol) and basic yellow 28 (CAS number 54060-92-3, molecular weight: 433.52 g/mol) were used in the adsorption experiments. Basic yellow 28, which is used in textiles with azo group, ionizes in its aqueous solutions and forms positively charged ions and is therefore a cationic dye (Slimani et al 2014;Benkaddour et al 2020). Methyl violet 2B, known as triphenylmethane dyes because it has 3 aryl groups attached to a nitrogen atom interacting with one or two methyl groups, is a basic dye due to the positive charge on the amino group, and its aqueous solutions are purple while the powder is dark green (Bonetto et al 2015;Dahri et al 2015).…”

Black cumin seed pulp (C), as well as biochar (CC) produced via pyrolysis of black cumin seed pulp were used to remove methylene violet 2B (MV) and basic yellow 28 (BY28) from aqueous solution. Adsorption isotherms and kinetics were applied at 10, 25, and 35 °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 than 0. The adsorption capacities of BY28-C, BY28-CC, MV-C, and MV-CC were 212.8, 625, 164, and 909 mg g-1 at 25 °C, respectively. The adsorption of black cumin seed pulp and biochar data were examined with the Freundlich, Langmuir, Temkin, Dubinin-Radushkevich (D-R), and 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.
