“…In type H2, this wide loop has a heterogeneous pore structure with sizes ranging from 2-6 nm and more than 10 nm in size. Thus, adsorption-desorption di erences occur because they have heterogeneous sizes due to the blockage of smaller pores with a pore shape like a pile of paper with looser gaps (Grabi et al, 2021). The BET analysis data are presented in Table 1.…”

“…Figure 14 shows that there is a wavelength shift that is carried out by adsorption which will detect the functional group of the compound. the dye adsorption process is in uenced by the number of functional groups, types of functional groups, interaction processes, adsorbent chemistry (Grabi et al, 2021). The results of the FT-IR spectrum can be seen in Figure 14 showing the appearance of a peak at the wavenumber of 2854 cm −1 because it has been in contact with the adsorbate.…”

This research converts agricultural waste Longan (Dimocarpus longan) Peel is used in the adsorption process to reduce cationic dyes rhodamine-B and malachite green contaminants from aqueous solution. Longan (Dimocarpus longan) Peel was characterized by FT-IR, analysis XRD, SEM, BET, and TG-DTA. The characterization results show that Longan (Dimocarpus longan) Peel contains cellulose compounds and has a specific surface area 17.175 m2/g, with this Longan (Dimocarpus longan) Peel has the potential as a bio adsorbent. The adsorption capacity is proven by adsorption capacity (Qm) shows that the bioadsorbent adsorption of malachite green has a large adsorption capacity of 182.64 mg/g, while the adsorption capacity of rhodamine-B (Qm) reaches 52.557 mg/g and this bioadsorbent longan (Dimocarpus longan) peel is effective the adsorption was stable until the third cycle.

Metal pollutants produced by industrial wastewaters have become a global concern given their impact on the environment and human health. The purpose of this study was to assess the polyphenols content and the iron chelating activity in the peels of two pomegranate varieties. After the biomass characterization via FT-IR, point of zero charge and surface functional groups analysis, the lead adsorption was then investigated by batch method. Finally, the regeneration of the biomasses was performed by acidic desorption. Polyphenols content of the red peels extract was higher than the yellow one; 102.9±0.9 and 85.9±1.3 mg GAE/g of dry weight, respectively with a half iron chelation inhibitory concentration (IC 50 ) of 227.2±1.7 and 235.9±3.2 µg.mL -1 of extract, successively. For the adsorption isotherms of lead onto the red and yellow pomegranate peels, the Langmuir model was more fitting with an adsorption capacity (Q max ) of 90 and 89.25 mg.g -1 , respectively. The kinetic data corresponded better to the pseudo-second order model. The acidic desorption of lead was successful with a high percentage of recovery. The results demonstrate the effectiveness of these biomasses as biosorbents for lead removal from aqueous solutions with the possibility of their reuse.

“…However, studies have also shown that some biomasses can be used as biosorbents without pre-treatment, and these are known as natural biosorbents. Numerous biomass materials such bean peel [13], banana and orange peel [14], sunflower stem pith [15], weeds [16], Carica papaya wood [17], corn straw [18], tea waste [19], pine tree leaves [7], cashew nutshell [20], and pineapple leaf powder [21] have been used as natural biosorbents to remove dyes from wastewater. Limited studies have also explored the potential of using untreated seaweeds as a natural biosorbent for dye removal [22,23].…”

This paper presents a comprehensive analysis of the adsorbent capacity of five distinctly different biosorbents derived from untreated biomasses. The optimal adsorption capacity of seaweed (Laminaria digitata), horse chestnut husk, hazelnut husk, rapeseed residue, and whitewood to remove methylene blue (MB) dye was assessed by analysing the effects of particle size, pH, temperature, and initial dye concentrations. Furthermore, the adsorption kinetics, isotherms, and adsorption thermodynamics were investigated. The results showed that relatively high MB adsorption capacity was achieved by Laminaria digitata (~180 mg/g), in addition to a reasonable MB adsorption capacity of horse chestnut husk (~130 mg/g), hazelnut husk (~110 mg/g), and rapeseed residue (~80 mg/g). However, whitewood provides a relatively low adsorption capacity of below 20 mg/g. The best fit with experimental results regardless of biosorbent type was a pseudo-second-order kinetic model with the lowest mean absolute percentage error (ε, MAPE < 2.5%) and the highest correlation coefficients (R2 > 0.99). Although the pseudo-second-order kinetic model is often associated with chemisorption, the low enthalpy values (<29.30 kJ/mol) typically suggest that the adsorption process is more characteristic of physisorption, which involves weaker van der Waals forces rather than the stronger covalent bonds of chemisorption. This proposed a multi-step adsorption process involving both physisorption and chemisorption. The adsorption isotherm of Langmuir showed superior fitting results for Laminaria digitata and hazelnut husk. In contrast, rapeseed residue and horse chestnut husk fit better with the Freundlich adsorption isotherm. The Langmuir adsorption isotherms showed a maximum adsorption capacity of ~500 mg/g for Laminaria digitata, followed by horse chestnut husk (~137 mg/g), hazelnut husk (~120 mg/g), and rapeseed residue (~85 mg/g). The Gibbs free energy was negative for Laminaria digitata < horse chestnut husk < hazelnut husk < 0, which suggests that the removal of MB is thermodynamically favourable, as the adsorption process occurs spontaneously. The results of the study indicate that MB dye removal using untreated biomasses has the potential to be a low-cost valorisation option in the holistic whole life cycle valorisation pathway for Laminaria digitata, horse chestnut husk, and hazelnut husk.
