“…They were contributing to the surface charge as the acidic groups. Carbonyl group (C=O) stretching vibration corresponded to the presence of ketone and aldehyde groups obtained in the range 1650 cm −1 to 1750 cm −1 associated with the surface polarity 38 , 39 . Wave number 1400 cm −1 to 1600 cm −1 peaks represented C=C groups having a cyclic arrangement of atoms with alternate double bonds, representing the presence of benzene rings, showing the presence of aromatic compounds, and improving the adsorption capacity.…”

This study investigates the use of carbonized Himalayan Chir Pine Biomass, known as Chir Pine Activated Carbon (CPAC), as an eco-friendly and cost-effective adsorbent for efficient industrial dye removal, with a focus on environmental sustainability. By applying different additive treatments, four adsorbents (C1, C2, C3, and C4) were formulated. CPAC was synthesized through pyrolysis and characterized using various analytical techniques including FE-SEM, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC). The adsorption capacity of CPAC was evaluated using Malachite Green (MG) dye as a model contaminant. FE-SEM images revealed high porosity (~ 10 µm) and a high surface area (119.886 m2/g) as confirmed by BET testing. CPAC effectively removed MG dye within 30 min at a solution pH of 7. Langmuir and Freundlich isotherm models indicated both monolayer and multilayer adsorption, while kinetic models suggested chemisorption. The regeneration efficiency was assessed using 0.1 N HCl over five consecutive cycles, with C4 demonstrating a high regeneration tendency of 85% and only a 9% reduction in adsorption ability after the fifth cycle. The developed CPAC shows excellent potential for use in the textile, paper, and leather industries for industrial dye adsorption, contributing to the protection of aquatic ecosystems. Additionally, CPAC can be utilized in other water and air purification applications.

“…The CNS AC can be prepared by chemical activation using ZnCl2 [13], KOH [11,14,15], or H3PO4 [17]. Acid impregnation can be applied in the protocol of AC preparation to improve the adsorption capacity of AC via the formation of functional groups on the AC surface [18][19][20][21]. However, to the best of our knowledge, the CNS AC prepared after the acid impregnation has not been fully investigated for its dye adsorption performance.…”

Adsorption is a widely used technique for the treatment of wastewater containing dyes, which are pollutants that can have serious impacts on the aquatic ecosystems. In this work, activated carbon (AC) was prepared from cashew nut shell (CNS) and used to adsorb methylene blue (MB) from solution. The CNS AC was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and nitrogen adsorption-desorption isotherms. The adsorption behavior of MB on CNS AC was investigated by varying the initial solution pH, adsorbent dosage, and initial MB concentration. The results showed that the CNS AC was effective for MB removal, with an adsorption capacity of 24.8 mg/g. The adsorption nature of MB onto the CNS AC surface was explored by analyzing the experimental data using isotherm and kinetic models. The Freundlich and Dubinin-Radushkevich (D-R) isotherm models showed good agreement with the experimental adsorption equilibrium results. The mean adsorption energy was found to be 22.4 kJ/mol, indicating chemical adsorption. The adsorption of MB on the CNS AC followed pseudo-second-order kinetics. This study demonstrates the potential application of CNS AC for MB removal.

“…Therefore, Pandanus stem will be a suitable lignocellulosic biomass for preparation of porous active carbons. Pandanus candelabrum originated from Pandanus plant (Screw pine), which belongs to the family Pandanaceae which comprises about 700 species and is widely distributed in tropical and subtropical regions (Fillaeli et al, 2019). They are found in the regions of South-East Asia, Pacific islands, Madagascar, Indian Ocean islands, India and West Africa.…”

Pandanus candelabrum stem, a new precursor, was used to synthesise activate carbon. The effect of sodium hydroxide, NaOH, zinc (II) chloride, ZnCl2 and phosphoric acid, H3PO4, different agents on prepared adsorbents was investigated. The adsorbents were prepared with chemical agents and carbonized at 400 oC for 1 hour. Surface morphology, elemental composition and functional groups were analysed with scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and fourier transform infrared spectroscopy (FTIR), respectively. The image analysis showed the presence of both micropores and mesopores in the adsorbents. The H3PO4 activated carbon had the maximum surface area (2648 m2/g), pore volume (1.683 cm3/g) and highest adsorption for iodine and methylene blue were 541 and 105 mg/g. Pandanus candelabrum stem is an alternative material that can be used to synthesis high porous adsorbent because is abundant, easy to access, inexpensive and readily available.
