“…Though the 'golden fiber' has plenty of applications, the stick is under-utilized and treated as agricultural waste (Ghosh et al 2019). Recently, an attempt has been made to produce activated carbon from lingo-cellulosic biomass of jute stick and has been evaluated for heavy metal removal from water (Ghosh et al 2020). India being the major jute producing country of the world, production of activated carbon from highly lignocellulosic jute stick holds immense potential.…”

“…The biomass was washed with water to remove dirt, followed by drying at 105 °C for 24 h, sizing (2 mm sieve), and stored for activation. Then around 250 g of processed jute stick biomass was impregnated with 85% ortho-phosphoric acid and processed for chemical activation at 450 °C for 2 h under constant nitrogen flow (50 ml min −1 ) of as per our earlier report (Ghosh et al 2020). Properties namely % carbon (CHNS analyzer, Model: Euro EA 3000; Italy), bulk density, moisture content, ash content, pH zpc (zero point charge), surface area (BET analyzer, Smart Instruments, India),average pore size, pore volume, particle size (LS particle size analyzer, Model: 13 320; Beckman Coulter, USA) etc.…”

“…Under this broad peak, the differentiation of individual peaks was difficult. Literature indicated that phosphoric acid derived carbons have strong peaks around 1200 cm −1 for H-bonded P=O, C-O stretching in P-O-C, or P=OOH (Ghosh et al 2020;Yaket and El-Deen 2016).…”

In this study, jute stick derived activated carbon (JSAC) has been evaluated as an adsorbent to remove textile dyes namely acid red-1 (AR-1), reactive orange-16 (RO-16), and methylene blue (MB) from water using the Box-Behnken model of response surface methodology (RSM). The direct and interaction effects of four independent process parameters namely solution pH, initial dye concentration, adsorbent dose, and time were investigated and optimized for textile dye by using ANOVA. The optimum conditions for maximum % dye removal were found to be pH-3, initial dye concentration-500 mg L −1 , adsorbent dose-0.9 gL −1 , and time-110 min for AR-1; pH-3, initial dye concentration-350 mg L −1 , adsorbent dose-1.5 g L −1 , and time-110 min for RO-16, and pH-11, initial dye concentration-415 mg L −1 , adsorbent dose-0.7 g L −1 , and time-86 min for MB, respectively. Adsorption equilibrium investigations were carried out with Langmuir, Freundlich, and Jovanovic models. Based on error analysis, Langmuir isotherm was found the best-fitted model with maximum adsorption capacities of 588.2, 156.3, and 384.6 mg g −1 for AR-1, RO-16, and MB, respectively. The dimensionless factor, R L values (range: 0.0152-0.2665) also indicated spontaneous and favorable adsorption of studied dyes onto JSAC. Dye loaded adsorbents were easily regenerated with 0.1 M HCl (for MB) and 0.1 M NaOH (for AR-1/RO-16) and reused up to the 4th cycle. The present investigation indicated that JSAC, with a highly porous and stable structure coupled with various functional groups, holds immense potential as a new adsorbent for textile dyes.

“…JDAC was prepared from jute sticks using H 3 PO 4 as an activating agent, reported by Rakesh Kumar Ghosh et al [60] The jute stick powders were mixed with H 3 PO 4 (1 : 5 w/w) and heated at 100°C for 2 hours, and this mixture was heated at 450°C for 2 hours in an N 2 environment. After washing and neutralization, the resultant product was dried at 105°C for 24 hours to obtain dried JDAC.…”

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.
