“…The loss of activity during the reusability assays in this study is significantly lower than those previously exemplified, which used immobilization by the adsorption method, confirming that immobilization by chemical methods prevents enzyme leaching. Hoinacki da Silva et al 37 treated biochar with citric acid for enzyme immobilization using glutaraldehyde as a crosslinking agent. The interaction of glutaraldehyde with citric acid-treated biochar was based on physical adsorption, such as hydrogen bonding and van der Waals forces.…”

“…The organic acid can be used in the immobilization by the covalent bonding method, as it provides groups for the binding of glutaraldehyde. 37,41 On the other hand, Lonappan et al 42 used citric acid to functionalize carbons aiming at enzyme immobilization by adsorption, but laccase immobilization was lower in functionalized materials.…”

“…Modified activated avocado seeds at 1000 °C and chemically treated with and without H 3 PO 4 and with and without carbonization were used to depigmentation of six dyes, and it was reported that the adsorption efficiency was influenced by the surface acidic groups of the carbonized adsorbent [26]. In addition, other avocado-derived materials were previously reported as adsorbents for removal of heavy metals [27][28][29][30], some dyes, and organic pollutants [31][32][33][34].…”

In the current investigation, an efficient low-cost nano-scaled material was prepared from waste avocado seeds (NASs) and employed as a sustainable nanosorbent for removal of hexavalent chromium ions. The adsorption and surface characteristics with respect to the availability of functional groups, basic component elements, and structural properties of NASs were achieved by different techniques. Analysis of NASs referred to the presence of carbon and oxygen contents providing 97.21%. The NASs particles were homogenously identified and ranged between 18.68 and 19.05 nm. The impact of various affecting adsorption parameters on hexavalent chromium ions removal was elaborated and optimized at pH 2.0, NASs dose 10 mg, contact time 30 min, and temperature 25 °C by the batch adsorption assay. Fifteen linear and nonlinear modeling tests were applied to evaluate the adsorption isotherms and arranged in the following fitting order: Tempkin < BET < Dubinin-Radushkevich < Generalized < Halsey ˂ Flory–Huggins < Freundlich < Harkins–Jura ˂ Langmuir for linear formulas and Weber-van Vliet < Langmuir < Generalized < Radke–Prausnitz (II) < Radke–Prausnitz (III) < Fritz-Schlunder IV < Baudu < Multilayer < Fritz-Schlunder V < Toth for nonlinear formulas with 2 to 5 parameters. Linear and nonlinear pseudo-second-order models, intraparticle diffusion, and Elovich models were also scrutinized, and both pore diffusion and film were similarly involved in the rate-limiting step. The values of ΔS° (0.21 kJ/mol), ΔH° (− 41.02 kJ/mol) and ΔG° (− 28.30 to − 19.97 kJ/mol) at high concentration of hexavalent chromium (50 mg L−1) and a temperature range of 20–60 °C reflected the disordering, spontaneously exothermic adsorption process. The activation energy (Ea) was also confirmed to include the diffusion process at the activation energy in the rate-limiting step. The potential application of NASs in hexavalent chromium removal from wastewater, seawater, and tap water as real aqueous matrices referred to excellent percentage removal values in the range from 98.44 to 98.86%. Based on the outlined results, one can deduce that excellent performance and efficiency for removal of high hexavalent chromium concentration at high temperature, low nanosorbent mass, and low pH from different aqueous matrices were accomplished by the evaluated NAS nanosorbent. Accordingly, the investigated NAS nanosorbent is recommended to apply in high stress industrial and wastewater treatment plants.
