Punica granatum shell (PGS), a solid waste, was prepared and characterized by point of zero charge measurement, Fourier transform infrared spectroscopy, scanning electron microscopy, N2 adsorption–desorption curves, and Boehm titration technique. The ability of PGS biosorbent to remove a basic dye, crystal violet (CV), from aqueous solutions by batch mode was investigated. The effects of pH, biosorbent dosage, contact time, and initial dye concentration on the biosorption capacity were studied. CV uptake was favorable at pH values ranging from 5 to 10. The contact time required to obtain the maximum biosorption was 2 h at 298 K using 0.6 g of biosorbent. The nonlinear pseudo‐second order kinetic model provided a best fit to experimental data when compared to pseudo‐first order and Elovich kinetic models. The equilibrium biosorption isotherm was studied according to nonlinear Langmuir, Freundlich, and Redlich–Peterson isotherm models. Regeneration of PGS was obtained using acetic acid as eluent. This study demonstrated that PGS is an effective low‐cost biosorbent for the removal of CV from aqueous solutions.

Cellolignin, a by-product from the wood processing industry, was studied as a new, eco-friendly adsorbent for the removal of methylene blue cationic dye from aqueous solutions, using a batch adsorption procedure. Experimental data were processed in order to study the equilibrium, thermodynamics, and kinetics of methylene blue adsorption onto cellolignin. Between the two studied isotherm models (Freundlich and Langmuir) the Langmuir model better described the equilibrium adsorption data at temperatures higher than 25 °C; the mean free energy (E) values obtained from the Dubinin-Radushkevich isotherm model show that the sorption of dye occurs via surface electrostatic interactions with the active sites of the cellolignin. The equilibrium data were used to calculate the free energy, enthalpy and entropy changes, and isosteric heat of adsorption (ΔH X ). Results confirm the feasibility and the endothermic nature of the adsorption process, suggesting that adsorption is a physico-chemical process. The isosteric heats of adsorption indicated energetic heterogeneity of adsorption sites and possible interactions between the adsorbed dye molecules. Kinetic assessment suggests that the adsorption process followed a pseudosecond order model and the rate-limiting step may be the binding of dye onto the adsorbent surface. The diffusion models show that intraparticle diffusion is not the sole rate-limiting step; the external mass transfer also influences the adsorption process in its initial period.

“…Through conversion of sesame stalks into carbon, unwanted agricultural waste would be converted into a useful, value‐added sorbent, that could be used to treat wastewater. At present, the carbons from agricultural residues are used to adsorb volatile organic compounds in contaminated air 11, heavy metals 12–14, dyes 15, 16, and other organic pollutants 17 in contaminated water, while little research has focused on the preparation of sorbents for the removal of polycyclic aromatic hydrocarbons (PAHs) from water.…”

This work explored the performance of sesame stalk-based carbon prepared at different carbonization temperatures and activated by potassium hydroxide in the removal of phenanthrene from an aqueous solution. At a carbon concentration of 10 mg/32 mL and a carbonization temperature of 7008C, the removal efficiency of phenanthrene approached 100%. Furthermore, with the presence of acenaphthene and naphthalene as co-contaminants, the removal efficiency of phenanthrene by the prepared carbon was 99.60%, which was comparable to that by the commercial carbon. Hydrophobic interactions influenced phenanthrene removal, and partitioning appeared to be the dominant mechanism for phenanthrene removal from aqueous solution by sesame stalk-based carbon. The results obtained from this work should provide insight into the reuse of agricultural residues, and also suggest a new avenue for the removal of polycyclic aromatic hydrocarbons from contaminated water utilizing carbon prepared from agricultural residue.
