Study of Characterization of Activated Carbon from Coconut Shells on Various Particle Scales as Filler Agent in Composite Materials

Abstract

Activated carbon (AC) derived from coconut shells (CS-AC) was obtained through pyrolysis at 700℃ and subsequently activated with H3PO4. AC was ground in a Wiley mill several times to form powder particles at particle scales of 80, 100, and 200 meshes. The characterization of the AC was studied using scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), Fourier-transform infrared spectroscopy (FT-IR), and surface area analysis (SBET). The CS-AC-200 mesh resulted in a higher percentage of mesopores and surface area. This particle size had a larger surface area with angular, irregular, and crushed shapes in the SEM view. The smaller particles had smoother surfaces, less wear, and increased curing depth and ratio of the hardness of the resin composite. Based on the characterization results of the AC, it is evident that CS-AC with a 200 mesh particle size has the potential to be used as a filler in biocomposites.

Efficient Adsorption of Methyl Orange on Nanoporous Carbon from Agricultural Wastes: Characterization, Kinetics, Thermodynamics, Regeneration and Adsorption Mechanism

“…The concentration evolution of the filtrates at the different contact times was followed at a wavelength of 463 nm. The quantity of MeO dye adsorbed in milligrams onto grams of nanoporous carbon at time t (mg/g) is shown in Equation (8).…”

“…In recent years, biochars synthesized from agricultural residues have been widely used as adsorbents to treat colored effluents due to their high porosity, high specific surface area and high adsorption capacity [5]. These biochars can be prepared by carbonization of any material containing a high proportion of carbon, such as wood [6], almond shells [7], coconut shells [8] or olive waste [9], by a high-temperature and long-duration pyrolysis treatment followed by chemical activation, or simultaneously with chemical activation [10]. Moringa oleifera is an abundant plant species in tropical and subtropical regions.…”

Utilization of Sapwood Waste of Fast-Growing Teak in Activated Carbon Production and Its Adsorption Properties

“…Furthermore, activated carbon has high adsorption for anions, cations, and molecules in the form of organic and inorganic compounds (Lubis, 2021). Prior literature documented that activated carbon has been used since the prehistoric age and plays an important role in various utilizations (Dungani et al, 2022). On an industrial scale, activated carbon is generally used for adsorbents, liquid and gas separators, and catalyst support materials (Sadir et al, 2022).…”
