“…The ultimate and proximate analyses, as well as the inorganic concentration in the kenaf samples, are shown in Table 1 . The results are within the range of typical agricultural and food processing residue compositions described in the literature [ 24 , 36 ]. The carbon content of raw kenaf is estimated to be around 47.32 wt%, according to the elemental composition of ultimate analysis.…”

“…After fibre extraction, the rest of the plant is either left in nature or burned for heating or cooking, which plainly pollutes the environment. Furthermore, kenaf is regarded to be one of the most promising plants, leads to improved agricultural practices, enhanced processing processes, and research on future development [ 24 ]. Kenaf is a tropical annual herbaceous plant that is used in agriculture.…”

“…The optimal calcination temperature and time were determined with a thermogravimetric analysis. A mass (10 g) of each biomass was calcinated from 30 • C to 800 • C at 10 • C min −1 rate [30][31][32]. The carbon content and yield were evaluated for the obtained biochar.…”

This study reports the adsorption capacity of lead Pb2+ and cadmium Cd2+ of biochar obtained from: peanut shell (BCM), “chonta” pulp (BCH) and corn cob (BZM) calcined at 500, 600 and 700 °C, respectively. The optimal adsorbent dose, pH, maximum adsorption capacity and adsorption kinetics were evaluated. The biochar with the highest Pb2+ and Cd2+ removal capacity is obtained from the peanut shell (BCM) calcined at 565 °C in 45 min. The optimal experimental conditions were: 14 g L−1 (dose of sorbent) and pH between 5 and 7. The sorption experimental data were best fitted to the Freundlich isotherm model. High removal rates were obtained: 95.96% for Pb2+ and 99.05. for Cd2+. The BCH and BZM revealed lower efficiency of Pb2+ and Cd2+ removal than BCM biochar. The results suggest that biochar may be useful for the removal of heavy metals (Pb2+ and Cd2+) from drinking water.

“…Several investigations have examined the characterization and the pyrolysis of various lignocellulosic materials such as palm kernel shells, corn cob, peanut shell, coffee husk [15], spent coffee grounds [16], Posidonia oceanica [17], kenaf stems [18] and grape marc [19]. Although the energy valorization values of olive [20,21], date waste [4,22,23], wheat straw [24,25] and Aleppo pine husks [26][27][28] are found in the literature, no information is available about the determination of reaction kinetics of C. monspeliensis using thermogravimetric analysis (TGA).…”
