“…Similar to the bio adsorbents under study, other biomaterials, after the adsorption process, were characterized by FTIR and showed the presence of similar functional groups, for example, Sakura residues showed the presence of groups such as -CH, C=O, which favor Cr (VI) adsorption [50]; sugar cane bagasse showed some functional groups responsible for Ni (II) adsorption, such as, OH group attributed by a broad absorption band shown at 3350 cm −1 [10]. Activated coffee and coffee husk also showed the presence of the OH group due to the bands located at 1440, 1364, 698, and 626 cm −1 , which denotes the interaction with Ni (II) ions [51].…”

“…For this reason, efforts have been made to remove heavy metals present in effluents through the implementation of different technologies such as solvent extraction, membrane filtration, ion exchange, reverse osmosis, chemical precipitation, oxidation, photocatalysis, among others [9]. However, these methods have limitations, such as the generation of toxic chemical sludge, incomplete metal removal, low efficiency, high energy, and reagent requirements [10].…”

The objective of this study was to prepare bio adsorbents from agro-industrial wastes from yam starch (YSR) and plantain (PSR) production for its use in the removal of Cr (VI) and Ni (II) in aqueous solution in batch and continuous packed-bed column systems. Bromatological analysis showed that the biomaterials are rich in cellulose, lignin, hemicellulose, and SEM micrographs that evidence a mesoporous structure characteristic of materials of lignocellulosic origin. FTIR evidenced functional groups such as hydroxyl, carbonyl, and methyl, possibly involved in the uptake of metal ions. EDS and FTIR analysis after adsorption confirmed that the retention of the metals on the surface of the adsorbent materials was successful. Cr (VI) and Ni (II) removal efficiencies above 80% were achieved using YSR and PSR in batch systems at the different conditions evaluated. The optimum conditions for removing Ni (II) on PSR were a bed height of 11.4 cm and a temperature of 33 °C, while for YSR, they were: 43 °C and 9 cm for temperature and bed height respectively. The variable with the most significant influence on the removal of Cr (VI) in a batch system on the two bio adsorbents was temperature. In contrast, the adsorbent dose and temperature are relevant factors for PSR Ni (II) removal. Therefore, the residues from the preparation of yam and plantain starch have high potential for removing heavy metals from wastewater and are presented as an alternative for their final disposal.

“…The dimensionless separation factor R L is given in Equation ( 2) which is an essential feature of Langmuir isotherm [15]. If R L = 0, the process is said to be irreversible, if R L = 1, it is linear, if R L > 1, it implies an unfavourable adsorption and if 0 < R L < 1, it's a favourable adsorption.…”

“…Adsorption kinetics describes the adsorption mechanism as well as estimates the time required for obtaining equilibrium concentration of metal ions onto the biomass [6]. It measures the efficiency of the process and shows a large dependence on physical and/or chemical characteristics of the sorbent material [15].…”

This study was aimed to investigate Pb(II) and Cu(II) ions removal ability from aqueous solution by cassava root husks (CRH) as a cheap, sustainable and eco-friendly bioadsorbent. The CRH was characterized by Fourier Transform Infrared (FTIR) spectroscopy which indicated the availability of various functional groups for metal coordination and the result was supported by elemental analysis studies. UV-Visible spectral studies indicated the presence of oxalate ( 2 2 4C O − ) and it could possibly interact with metal ions to give rise to a stable chelated coordination complex which affects metal ions removal efficiency. Bioadsorption process was carried out as a function of metal concentration, contact time, pH of the solution, particle size, and dosage of the adsorbent. Experimental results indicated the optimal adsorption condition of pH 4 for both Pb(II) and Cu(II) ions, dosage of 0.1 g/0.1L and 1 g/0.1L for Pb(II) and Cu(II) ions respectively, adsorption equilibrium time of 2 and 25 minutes for Pb(II) and Cu(II) respectively, and concentration of 0.5 mg/L for both metal ions. Kinetic data best fitted pseudo-second-order model and not the pseudo-first-order model. Equilibrium data best fitted the Freundlich model than the Langmuir model. Specific surface area and pore volume studies indicated that CRH is non-porous and hence rapid adsorption kinetics is expected. Supporting the experimental results, molecular modeling studies performed using Schrödinger software predicted several sites in the structure capable of docking with metal ions.
