The ability of coconut shell biochar (CSB) and acid-base modified coconut shell biochar (MCSB) for the removal of copper (Cu(II)) from aqueous solution is examined. The basic characteristics of CSB as well as MCSB such as proximate analysis, pH value, surface area, surface morphology and surface functional groups are investigated. The individual effect of initial concentration and contact time on the removal efficiency of Cu(II) by CSB and MCSB was determined using one variable at a time (OVAT) approach. In addition, the response surface methodology (RSM) approach is applied to determine the combined effects of variables (pH, contact time and particle size) on the removal efficiency of Cu(II) ion. The RSM results for the MCSB showed that Cu(II) maximum removal efficiency is 99.50% at pH 7, contact time of 60 min, and particle size of 0.60 mm, respectively. It can be concluded that MCSB has greater potential than CSB to be utilized as an adsorbent for Cu(II) removal in water bodies.

“…It has been stated that if this energy is within the range 8 kJ/mol < E < 16 kJ/mol, the adsorption mechanism is ionic exchange, if E < 8 kJ/mol, the adsorption mechanism is physical adsorption, and if E > 16 kJ/mol, the adsorption mechanism is diffusion (Savran et al 2017).…”

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.
