“…9). However, the thermodynamic outcomes indicate that the biosorption process involved physical interactions (Vander Waal's and strong elctrostatic interactions majorly as the value of ΔH•= -14.782 kJ/mol) (Hernández-Francisco et al, 2020). The applicability of pseudo-second-order kinetic model indicates the probability of chemisorption as a major biosorption mechanism.…”

Inorganic metal pollution is becoming more prevalent as industrialization progresses. Despite being an essential element, Zn (II) can be detrimental if consumed in excess. In this study, the possibility of using Lantana camara leaves to prepare a biosorbent that can eliminate Zn (II) ions from contaminated wastewater solutions was investigated. BET surface area, FTIR and SEM analysis were carried out to characterize the prepared Lantana camara leaves biosorbent (LCLB). It was reported that increasing biosorbent dosage and contact duration improves Zn (II) ion removal while it decreases with rising initial concentrations of Zn (II) ions and temperature. At pH 6, 5 g adsorbent dosage, and 45 minutes contact time, excellent removal capabilities (85.06%) were reported. The pseudo-second-order rate model fit the kinetics of Zn (II) adsorption well (R2 > 0.998), and the predicted adsorption capacity of the model agreed well with the experimental outcomes. The Langmuir isotherm (R2 > 0.996) was the best suited isotherm model for Zn (II) adsorption onto LCLB, implying monolayer adsorption. Thermodynamic experiments revealed that Zn (II) adsorption on the biosorbent's surface was spontaneous and exothermic. Desorption studies implied that the biosorbent can be recycled effectively up to two cycles. An investigation of the maximum adsorption capabilities of different untreated biomaterial-based residues found that LCLB is an effective, inexpensive, and environmentally acceptable biosorbent for use in the removal of contaminants from polluted aqueous media.

“…Firstly, the coefficient of determination for Langmuir is almost unity and higher than the coefficient of determination for Freundlich. Secondly, it is observed that 1/n value is below unity, which further implies a governing chemisorption process [55,56]. Chemisorption involves the formation of chemical bonds between the lead ions and functional groups on the surface of carbon microspheres, which is expected since the activation using a relatively strong acid such as phosphoric acid would have induced such functional groups.…”

The removal of lead metals from wastewater was carried out with carbon microspheres (CMs) prepared from date palm leaflets using a hydrothermal carbonization process (HTC). The prepared CMs were subsequently activated with phosphoric acid using the incipient wetness impregnation method. The prepared sample had a low Brunauer–Emmet–Teller (BET) surface area of 2.21 m2·g−1, which increased substantially to 808 m2·g−1 after the activation process. Various characterization techniques, such as scanning electron microscopy, BET analysis, Fourier transform infrared, and elemental analysis (CHNS), were used to evaluate the morphological structure and physico-chemical properties of the CMs before and after activation. The increase in surface area is an indicator of the activation process, which enhances the absorption properties of the material. The results demonstrated that the activated CMs had a notable adsorption capacity, with a maximum adsorption capacity of 136 mg·g−1 for lead (II) ions. This finding suggests that the activated CMs are highly effective in removing lead pollutants from water. This research underscores the promise of utilizing activated carbon materials extracted from palm leaflets as an eco-friendly method with high potential for water purification, specifically in eliminating heavy metal pollutants, particularly lead (II), contributing to sustainability through biomass reuse.

Cellulose-based materials have been advanced technologies that used in water remediation. They exhibit several advantages being the most abundant biopolymer in nature, high biocompatibility, and contain several functional groups. Cellulose can be prepared in several derivatives including nanomaterials such as cellulose nanocrystals (CNCs), cellulose nanofibrils (CNFs), and TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidized cellulose nanofibrils (TOCNF). The presence of functional groups such as carboxylic and hydroxyls groups can be modified or grafted with organic moieties offering extra functional groups customizing for specific applications. These functional groups ensure the capability of cellulose biopolymers to be modified with nanoparticles such as metal-organic frameworks (MOFs), graphene oxide (GO), silver (Ag) nanoparticles, and zinc oxide (ZnO) nanoparticles. Thus, they can be applied for water remediation via removing water pollutants including heavy metal ions, organic dyes, drugs, and microbial species. Cellulose-based materials can be also used for removing microorganisms being active as membranes or antibacterial agents. They can proceed into various forms such as membranes, sheets, papers, foams, aerogels, and filters. This review summarized the applications of cellulose-based materials for water remediation via methods such as adsorption, catalysis, and antifouling. The high performance of cellulose-based materials as well as their simple processing methods ensure the high potential for water remediation.
