“…Its capacity and versatility is mainly due to its porous texture that provides it with a large surface area, its controllable pore structure and its thermo-stability [140]. Its chemical nature can also be easily modified by chemical treatment in order to enhance its properties.…”

“…In addition, since it is a less specific adsorbent, its capacity is easily saturated by the complex liquid matrix of wastewaters and its regeneration is difficult when used as CWS bed. In fact, the biggest barrier to the general use of activated carbon is its cost and the difficulties associated with regeneration [137,140]. Activated carbon is quite expensive and the higher the quality the greater the cost.…”

“…Among these ACs have proved to be one of the most promising adsorbent material for storage of hydrogen due to their availability, low cost and with tunable surface area. Natural raw materials like corn cob [29,30], rice husks [31,32], nut shells [33], oil seeds [34], coffee bean [35], hemp stem [36], corn stalks [37], etc. have been studied for hydrogen storage.…”

Abstract. Activated carbons (ACs) are being used as energy storage material especially for hydrogen storage application. In the present work, AC materials were synthesized from jute fibers, activated and treated using KOH to increase the porosity of samples. These AC samples retained the fibrous structure even after chemical activation at high temperature of 700°C. Channel like structures were formed which helps to increase the hydrogen storage capacity. The surface area of these samples varied from 380 to 1220 m 2 /g due to carbonization and activation treatment. The sample with high surface area of 1224 m 2 /g showed a high hydrogen uptake capacity of 1.2 wt.% at 30°C and 40 bar of H 2 gas pressure. This sample also showed a high pore volume of 0.74 cm 3 /g. These results indicate that the raw material jute fibers can be used as hydrogen storage medium after thermal and chemical treatment which increases the surface area and micropore volume.

“…The SMFW consists of sawdust and rice husk majorly. Previous study using sawdust as AC by Foo & Hameed [5] and Moodley et al [6] and rice husk as AC by Khan et al [7], Chen et al [8], Kumagai et al [9] and Ding et al [10] have generated highly porous carbonaceous carbon. These reports showed that both components of sawdust and rice husk are suitable as a potential precursor.…”

This study focuses on activated carbon preparation from spent mushroom farming waste (SMFW) via chemical activation using Box-Behnken design (BBD) of Response Surface Methodology (RSM). Potassium hydroxide (KOH) functions as activating reagent and it plays an important role in enhancing the activated carbon porosity. Three input parameters and two responses were evaluated via this software generated experimental design. The effects of three preparation parameters of impregnation ratio, activation time and activation temperature as well as two responses of carbon yield and iodine number were investigated. The optimum conditions for preparing activated carbon from SMFW was found at SMFW: KOH impregnation ratio of 0.25, activation time of 30 min and activation temperature of 400 o C which resulted in 28.23 % of carbon yield and 314.14 mg/g of iodine number with desirability of 0.994. The predicted results were well corresponded with experimental results. This study is important in economical large scale SMFW activated carbon preparation for application study of adsorption process for metal treatment in wastewater with minimum chemical and energy input.Keywords: activated carbon, spent mushroom farming waste, Box-Behnken design, response surface methodology Abstrak Kajian ini memfokuskan penyediaan arang teraktif daripada sisa tanaman cendawan terpakai melalui reka bentuk box-behnken (BBD) dari kaedah gerak balas permukaan (RSM). Potasium hidroksida (KOH) berperanan sebagai agen pengaktifan dan penting untuk meningkatkan liang arang teraktif. Tiga parameter input dan dua respon telah dinilai oleh perisian ini yang dihasilkan oleh rekabentuk eksperimen. Kesan daripada penyediaan tiga parameter iaitu nisbah pemadatan, masa pengaktifan dan suhu pengaktifan serta dua respon iaitu hasil arang teraktif dan nilai iodin telah disiasat. Keadaan optimum dalam penyediaan arang teraktif telah didapati pada nisbah SMFW: KOH iaitu 0.25, tempoh pengaktifan selama 30 min dan suhu pengaktifan 400 °C, di mana ia menghasilkan jumlah maksimum arang teraktif sebanyak 28.23 % dan nilai iodin yang boleh diterima iaitu sebanyak 314.14 mg/g dengan ketepatan 0.994. Keputusan yang telah diramalkan adalah seiring dengan keputusan eksperimen. Kajian ini adalah penting dalam penyediaan arang teraktif secara berskala besar dengan ekonomi daripada sisa tanaman cendawan terpakai untuk kajian proses penjerapan terhadap rawatan logam dalam air sisa dengan input bahan kimia dan tenaga yang minimum.
