“…They can be used for the production of Activated Carbon with a high adsorption capacity, considerable mechanical strength, and low ash content (Savova et al, 2001). Literature survey indicates that there have been many attempts to obtain low-cost Activated Carbon or adsorbent from agricultural wastes such as wheat, corn straw, olive stones, bagasse, birch wood, miscanthus, sunflower shell, pinecone, rapeseed, cotton residues, olive residues, pine rayed, Eucalyptus maculata, sugar cane bagasse, almond shells, peach stones, grape seeds, straw, oat hulls, corn stover, apricot stones, cotton stalk, cherry stones, peanut hull and rice straw (Abbas, 2021;Aghababaei et al, 2021;Charoensook et al, 2021;Cheng et al, 2021;Demiral et al, 2021;Thithai & Choi, 2020;Wang et al, 2021). Senegalensis saba hulls are refrozen residue in the environment while they contain a large amount of carbon (Demirbas, 2009;Salamata et al, 2020) and other compounds based on silica and carbonate.…”

Adsorption on activated carbon is one of the most widely used methods for the removal of dyes. The objective of this study is to valorize the shells of Saba senegalensis from local product in Senegal in the form of activated carbon and to test its effectiveness for the removal of methyl violet. The study was carried out in batch mode for a maximum duration of one hour with 100 mL of solution treated at 600 rpm. The results reveal that the granulometry 500 µm gives the best yield with an adsorption rate of 95%, a mass of adsorbent of 0.2 g gives an adsorption capacity of 20 mg/g, the contact time of one hour with a capacity of 5 mg/g. The study also showed that the adsorption process of methyl violet is described by the pseudo-second order kinetic model with correlation coefficient of 0.99. Two adsorption isotherms were studied, and the results revealed that the Freundlich model better describes the adsorption of methyl violet on Saba senegalensis shell residue-based activated carbon (SSSRAC). The results indicate that SSSRAC could be used as a low-cost alternative for the removal of textile dyes such as methyl violet.

“…Researchers have reported the production of AC from agricultural wastes, such as pistachio shells using KOH potassium hydroxide agent (Lee et al, 2021;Nazem et al, 2020), coconut husk using KOH treatment, and coffee endocarp using KOH (Yuliusman et al, 2019). AC has also been produced from corn stover through thermogravimetric analysis (Thithai and Choi, 2020); sengon wood wastes, corn hulls, and corn stover through carbonization (Gale et al, 2021;Hendrawan et al, 2019;Ko et al, 2018); and sunflower shells, pinecones, rapeseed, cotton, and olive residues through pyrolysis (Dorado et al, 2020). Hesas et al (2013) used apple waste to produce AC through microwave-assisted phosphoric acid (H 3 PO 4 ) activation.…”

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.

Physicochemical Properties of Activated Carbons Produced from Coffee Waste and Empty Fruit Bunch by Chemical Activation Method

In this study, coffee waste (CW) and empty fruit bunches (EFB) were employed as precursors for the production of activated carbons by a chemical activation method. KOH, ZnCl2, and H3PO4 were used as activating agents along with their three mixing ratios of 1:0, 1:1, 1:3, w/w, and carbonization temperatures of 600 °C, 700 °C, and 800 °C were used to prepare these activated carbons. The highest yields of produced activated carbons were observed at 600 °C with a value of 45.20% for coffee waste and 48.20% for empty fruit bunch, with a 1:3 w/w (H3PO4) ratio. However, the maximum specific surface area was 3068 m2 g−1, and 2147 m2 g−1 obtained at 800 °C for coffee waste and empty fruit bunch activated carbons, respectively. The surface features of these products exhibited acute morphological changes, as were clearly noticed via SEM studies. Moreover, in the Van Krevelen diagram, it was also observed that both the H/C and O/C ratios were dramatically decreased to 0.0019 and 0.0759, and 0.0066 and 0.1659 for coffee waste and empty fruit bunch at 800 °C with a (1:3) potassium hydroxide and zinc chloride ratio, respectively, and this similar phenomenon was also supported by a thermal gravimetric analysis. All these results, together with the specific characteristics of the products, suggest that this scheme can be an effective strategy for the activated carbon production from such residues.
