“…In comparison with another 3 works [1][2][3] elemental analyses, %C of this work was closed to the data of Abhishek et al [1], due probably to the similar preparation of rice straw. The result of Suwiwat et al [3] which chemically activated the raw material by KOH before pyrolysis and it may affect carbon content of the adsorbent.…”

Abstract. This study focused on adsorption of atrazine in adsorbent synthesized from Rice Straw. Rice Straw biochar were used in the study as they exhibited significantly high adsorption capacity for pesticide. Briefly, rice straw was pyrolysis at 600• C under nitrogen then biochar was modified using H 3 PO 4 . Biochar were characterized for their physico-chemical characteristics. The elemental analysis of biochar was performed using CHNS Analysis. The surface area and pore volume of adsorbents were estimated using the Brunauer, Emmett, and Teller (BET Analysis). In parts of Batch adsorption experiments was performed in range of room temperature and were divided to 2 parts. Part 1: Study of the kinetics adsorption was investigated using two models, namely, the pseudo-first-order and the pseudo-second-order models. . From plotting between q t (mg/g) and time (t) shows the dynamics of the adsorption of atrazine onto the biochar at 15 ppm of initial atrazine concentrations. In general, atrazine was adsorbed quickly around 1-30 min. This could be due to fast mass transfer of solute from the solution to surface of adsorbent s as a result of concentration gradient of the solute. The study of the kinetics adsorption showed that the pseudo-second-order model best described the adsorption which agrees with chemisorption as the rate controlling mechanism.

This work deals with the preparation of activated carbon (AC) from Korch (Erythrina brucei) sawdust (EB), Bamboo (Arundinaria alpina) sawdust (AA), and Cassava peel (Manihot esculenta) powder (ME) to remove methylene blue (MB) from aqueous solution. The effect of temperature, chemical impregnation (H3PO4, ZnCl2, KOH and H2SO4) were done. The optimum temperature used to prepare activated carbon of EB, AA and ME were700 ℃ , 400 ℃ and 600 ℃ respectively. High surface area AC was obtained by chemical activation of biomaterial with H3PO4. The effect of various process parameters like pH, contact time, adsorbent dose on the efficiency MB removal was investigated. The optimum pH value and contact time for AC of EB, AA and ME was determined as 6, 5, 4 and 40, 50, 60 min respectively. The optimum adsorbent dose of EB, AA and ME were determined 0.04, 0.06 and 0.12g respectively in 25ml of solution. Thermodynamic analysis asserted endothermic and spontaneous nature of the system. Equilibrium data were represented better by Langmuir model than Freundlich which describes monolayer adsorption. The linear regression analysis of kinetic data confirmed that Pseudo-second order rate expression.

“…As a result, carbonaceous materials prepared from renewable and low-cost agricultural products, including agricultural byproducts and waste as precursors, which contain enough carbon in their structure, have attracted the interest of researchers all over the world. [6,8,11] The unique properties of these agriculturalproduct-derived materials include their carbon-like high-surface area, versatile porosity, and high electrical and thermal conductivity, allowing them to be used in many different applications. Various agricultural byproducts such as date palm leaves, [4,12,13] tal palm leaves, [14] Albizia procera leaves, [15][16][17] Syzygium cumini leaves, [8] taro stems, [18] rice husks, [19] Pithophora polymorpha, [20] tomato stems, [21] barley straws, [22] sunflower piths, [23] lotus stalks, [24] peanut shell, [25] carrot residue, [26] citrus fruits, [27] and orange peel [28] have been used as suitable precursors for the production of low-cost carbonaceous materials.…”

This article summarizes the preparation and applications of carbon derived from jute sticks and fibers that are low‐cost, widely available, renewable, and environmentally friendly. Both the fibers and sticks are considered ideal candidates of carbon preparation because they are composed of cellulose, hemicelluloses, and lignin, and contain negligible ash content. Various carbon preparation methods including simple pyrolysis, pyrolysis with chemical and physical activations are discussed. The impacts of several parameters including types of activating agents, impregnation ratio, and temperature on their morphology, surface area, pore size, crystallinity, and surface functional groups are also emphasized. Various treatments to endow functionalization for increasing the practical applicability, such as chemical, physical, and physico‐chemical methods, are discussed. In addition, applications of jute‐derived carbon in various practical areas, including energy storage, water treatment, and sensors, are also highlighted in this report. Due to the porous fine structure and a large specific surface area, the jute‐derived carbon could be considered as a powerful candidate material for various industrial applications. Finally, possible future prospects of jute‐derived carbon for various applications are pointed out.
