“…As shown in the data, after adsorption, these peaks shifted to lower wavenumber values of 3374 and 3349 cm −1 respectively, indicating that the -O-H groups of nano-LCE-MOT and LCE-MOT participated in the adsorption process, which in turn demonstrates the involvement of oxygen in the chemisorption of Zn (II) in the subsequent complexation process. The characteristic absorption peaks at approximately 1690 cm −1 for LCE-MOT and 1646 cm −1 for nano-LCE-MOT can be attributed to -C=O stretching in the carboxylic organic acid groups of the materials, which were shifted to lower wavenumber values of 1687 and 1657 cm −1 after adsorption and 1657 and 1643 cm −1 after desorption, respectively, as the possible result of the oxygen in the -C=O of nano-LCE-MOT and LCE-MOT forming complexes with the heavy metal ions [ 58 ]. The -OH in the carboxylic group exhibited characteristic absorption peaks for nano-LCE-MOT and LCE-MOT at 1464 and 1456 cm −1 , respectively, which disappeared after adsorption, proving that the -C=O bonds in the carboxylic organic acid groups participate in the chemisorption process.…”

Lignocellulose (LCE) was ultrasonically treated and intercalated into magnesium aluminum silicate (MOT) clay to prepare a nano-lignocellulose magnesium aluminum silicate polymer gel (nano-LCE-MOT) for the removal of Zn (II) from aqueous solution. The product was characterised using nitrogen adsorption/desorption isotherm measurements, Fourier-transform infrared spectroscopy, scanning electron microscopy and energy-dispersive X-ray spectroscopy. The conditions for the adsorption of Zn (II) on nano-LCE-MOT were screened, and adsorption kinetics and isotherm model analysis were carried out to explore the adsorption mechanism and achieve the optimal adsorption of Zn (II). Optimal adsorption was achieved at an initial Zn (II) concentration of 800 mg/L at 60 °C in 160 min at a pH of 4.52. The adsorption kinetics were explored using a pseudo-second-order model, with the isotherm adsorption equilibrium found to conform to the Langmuir model. The maximum adsorption capacity of the nano-LCE-MOT polymer gel toward Zn (II) is 513.48 mg/g. The materials with adsorbed Zn (II) were desorbed using different media, with HCl found to be the most ideal medium to desorb Zn (II). The optimal desorption of Zn (II) was achieved in 0.08 mol/L HCl solution at 65 °C in 60 min. Under these conditions, Zn (II) was almost completely desorbed from the adsorbents, with the adsorption effect after cycling being slightly different from that of the initial adsorption.

Commercial activated carbon is a type of adsorbent commonly used in adsorption processes. However, the use of commercial carbon in wastewater treatment is still limited, due to the scarce availability of precursors and their high cost. Biomass as an activated carbon precursor has been reported to have high efficiency in removing various heavy metals in wastewater. This study aims to review the potential of biomass-based activated carbon to adsorb heavy metals in terms of biomass constituent components, heavy metal removal, and future prospects. The method in this study is a systematic literature review, or SLR, to collect data from online databases such as Google Scholar, PubMed, and ScienceDirect. The results show that biomass-based activated carbon is effective in the removal of heavy metals in various types of wastewater. The removal effectiveness for different types of biomass ranged from 84–99% for Pb2+ ions, 55–92% for Cd2+ ions, 84–99% for Pb2+ ions, 96% for As2+ ions, 80–100% for Cr2+ ions, 25–97% for Fe2+ ions, 50–99% for Ni2+ ions, and 62–98% for Cu2+ ions, and 98% for Ti ions. These results show that heavy metals have different affinities to activated carbon from biomass, from all heavy metals, Fe2+ and Cd2+ ions have the lowest affinity, so the activated carbon used to remove Fe2+ and Cd2+ metals needs to be produced with higher porosity and surface area. The removal of heavy metals using activated carbon from biomass is limited by adsorbent dosage, contact time, solution pH, temperature, initial adsorbate concentration, particle size, and stirring speed. In future research, it is expected that activated carbon from biomass has a high adsorption capacity, is economical cost, is environmentally friendly and can be used on a larger scale.
