“…Additionally, both showed pronounced hysteresis loops at 0.5 relative pressure, proving that there are intermediate pores in the materials [ 29 ]. It can be classified as the combined type I/IV isotherms according to IUPAC classification [ 48 ]. Thus, a mesopore and micropore combination structure were visible in the two materials.…”

“…Inorganic membranes have demonstrated high permeability and selectivity but face challenges related to fabrication costs and scalability [17,18]. Polymeric membranes, following the solution-diffusion mechanism, encounter limitations due to the tradeoff between selectivity and permeability, hindering their industrial applicability [19,20].…”

This study investigates the potential of activated carbon derived from ripe plantain peels (PPAC) for carbon dioxide (CO2) capture. PPAC was prepared through carbonization and activation using H3PO4, and its unique properties were extensively characterized which revealed irregular sponge-like protrusions and well-defined pores under Scanning Electron Microscopy (SEM). Elemental analysis identified carbon, silicon, and oxygen as major components, corroborated by X-ray Diffraction (XRD) analysis indicating the presence of silicon oxide (SiO2), potassium oxide (K2O), and calcium oxide (CaO). Fourier Transform Infrared (FTIR) spectroscopy highlighted diverse functional groups on PPAC's surface. CO2 adsorption tests were conducted at 27°C and 40°C with varying pressures on PPAC particles of 150µm and 845µm sizes. Results revealed that CO2 adsorption capacity increased with escalating pressures. Remarkably, at 27°C, PPAC exhibited superior performance than at 40°C, attributed to a higher-pressure drop enhancing the driving force for CO2 adsorption. Larger particles (845µm) demonstrated higher adsorption capacity due to increased surface area, enhanced pore accessibility, and faster mass transfer. The Response Surface Methodology (RSM) conducted gave 2FI model as the most representative of the design data and showed high accuracy (R2=0.9973) and low error metrics (MSE=0.01697, RMSE=0.130269, MAE=0.109, MAPE=2.7244). The Adeq Precision value of 76.26 validated the model's reliability. Optimization using RSM yielded optimal CO2 adsorption values (9.69 mmol/g) at 27°C and 100 bars. PPAC emerges as a promising solution for CO2 capture, offering valuable prospects in mitigating emissions and addressing climate change challenges.

“…Adsorption using activated carbon (AC) is among the most versatile technologies as it can removes a variety of contaminants, including synthetic dyes 10 – 13 , heavy metals 14 , 15 , phenolic compounds 16 , pesticides 17 and other organic compounds. Moreover, this method is relatively inexpensive, and AC can be derived from various biomass wastes, including water hyacinth 18 , algae 19 , coconut shell 20 , apple waste 21 , andiroba shell 22 , durian peel 23 , tea residue 24 , pine sawdust 25 , and herbaceous plants 26 , among others. Some studies have shown that biomass-based AC are a feasible source of AC 10 , further reducing waste generated by factories and farming activities 27 .…”

Date palm stones are regarded as possible alternatives to activated carbon (AC) precursors with high potential for various environmental applications. In this research study, date palm stones derived activated carbon (DPSAC) was used as adsorbent for removing toxic remazol brilliant blue R (RBBR). The synthesis of DPSAC involved a chemical treatment using KOH and NaOH (1:1). Characterization of DPSAC revealed that it exhibited a BET surface area of 715.30 m2/g, Langmuir surface area of 1061.93 m2/g, total pore volume of 0.39 cm3/g, and average pore diameter of 2.15 nm. Adsorption uptake of RBBR increased (from 24.54 to 248.54 mg/g), whereas the removal percentage decreased (from 98.16 to 82.85%) when the initial RBBR concentration increased (from 25 to 300 mg/L). The adsorption process performed best under acidic conditions (pH 3), with an RBBR uptake of 98.33 mg/g. Because of the high R2 values (0.9906 and 0.9779) and low average errors (6.24 and 13.95%), this adsorption process followed the Freundlich isotherm and pseudo-first-order (PFO) models, respectively. The Langmuir adsorption capacity (Qm) was 319.63 mg/g. Thermodynamic parameters were − 11.34 kJ/mol for ∆H° (exothermic in nature), 0.05 kJ/mol K for ∆S° (increasing randomness level at solid–liquid interface), − 27.37 kJ/mol for ∆G° (spontaneous), and 6.84 kJ/mol for Ea (controlled by physisorption).
