“…The carbonization process involves cleavage of C-H and C-C bonds to form reactive free radicals, molecular reassemble, thermal polymerization, aromatic condensation and elimination of H2 [9,10,12]. Low heating rate can reduce adverse effects such as shrinkage, cracking and thermal stresses that may build up during carbonization.…”

The effects of various carbonization parameters on the COD reduction of Rhodamine B dye aqueous solutions using carbonized Elaeis guineensis frond fiber (EGFF) chars have been studied experimentally. The adsorbent with the particle size of <45 µm has been carbonized at temperature from 500-900 o C with carbonization duration of 1-3 h at a heating rate of 10-30 o C/min and nitrogen gas flow rate of 100-500 cm 3 /min. Carbonization temperature, carbonization duration, heating rate and nitrogen gas flow rate were significantly affecting the carbonization process. Statistical analysisresponse surface methodology (RSM)-face centered composite design (FCCD) was used to obtain the optimal carbonization conditions. The optimum condition for carbonization of EGFF was obtained at carbonization temperature of 899 o C, carbonization duration of 2.7 h, heating rate of 10 o C/min, and nitrogen flow rate of 243 cm3/min with 98.88 % of COD reduction of Rhodamine B

“…As one of the most important materials, carbon materials have attracted a lot of attention for their potential applications as automobiles, aerospace, defense, sports, gas storage, electrodes, filler, and catalyst supports [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. Especially, porous materials (including activated carbons, zeolites, and alumina powders) are useful materials for gas adsorption and storage [42][43][44][45][46][47][48][49].…”

People have been concerned about mercury emissions for decades because of the extreme toxicity, persistence, and bioaccumulation of methyl Hg transformed from emitted Hg. This paper presents an overview of research related to mercury control technology and identifies areas requiring additional research and development. It critically reviews measured mercury emissions progress in the development of promising control technologies. This review provides useful information to scientists and engineers in this field.

“…One of the most widely used techniques is adsorption by activated carbon (AC) coming from agricultural wastes which show greater potential for the treatment of wastewaters due to very large quantities, easy to get and very low costs [43,39]. For the above reasons, a wide range of agricultural wastes including banana and pomegranate peels [44] and rice husk [29], sugar beet pulp [37], corn wastes [1], tea waste and rice husks [54], walnut shells [42], chestnut shells [15], orange peels [23], walnut [33] and citrus limetta peel [49]. Lit et al [38] studied the abilities of biochars produced from six agriculture wastes (soybeans, corn stalks, rice stalks, poultry manure, cattle manure and pig manure) to remove atrazine pesticide from contaminated water.…”

The preparation of eco-friendly low-cost silkworm feces activated carbon (SFAC) for the removal of oxamyl pesticide from aqueous solution has been investigated in batch experiments. Structure and morphology of SFAC were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (SEM). The specific surface area and mean pore diameter were obtained as 75.219 and 0.2035 cm 3 g -1 , respectively. The effect of different physicochemical parameters such as initial oxamyl concentrations, activated carbon dose and contact time has been studied. The results showed that the oxamyl removal on SFAC was unaffected in the pH range of 2-10. The percent removal of oxamyl onto SFAC was 99.48% from aqueous solutions. The adsorption process attained equilibrium within 120 min of contact time. Equilibrium data were analyzed by the Freundlich, Langmuir and Dubinin-Radushkevich (D-R) isotherm models. Freundlich isotherm provided the best fit to the equilibrium data. Adsorption kinetic was fitted well by the pseudo-secondorder kinetic model. The results revealed that SFAC could be used a low-cost and eco-friendly alternative to other adsorbents for the oxamyl removal from aqueous solution.
