“…As reported by Daley at al. [9], good agreement is become increasingly popular and it has been discussed found between the PSD derived from the DS equation and recently [10]. At the present time, modeling is frequently the experimental distribution observed by STM on strongly based on the adsorption of N [11][12][13] ] with an average microporē width L around 0.75 nm.…”

“…The wide range of pore sizes makes ACs universal adsorbents, since they can accommodate almost all sizes of molecules. ACs are mainly prepared by carbonizing and activating natural and synthetic precursors which have high fixed carbon content, such as wood [1], coal, coconut shell [2], corn cobs, polyacrylonitrile [3], phenolic resin [4], and viscose rayon [5]. The activated carbons are employed in a wide spectrum of applications like air purification, wastewater treatment, solvent recovery, odor control and for personal protective clothes.…”

In this study, synthetic viscose rayon fabric has been used for preparing activated carbon fabric (ACF), impregnated with different concentrations of H 3 PO 4 . The effect of H 3 PO 4 impregnation on the weight yield, surface area, pore volume, chemical composition and morphology of ACF were studied. Experimental results revealed that both Brunauer-EmmettTeller surface area and micropore volume increased with increasing H 3 PO 4 concentration; however, the weight yield and microporosity (%) decreased. It was observed that samples impregnated at 70°C (AC-70) give higher yield and higher microporosity as compared to 30°C (AC-30). The average pore size of the ACF also gradually increases from 18.2 to 19 and 16.7 to 20.4 Å for 30°C and 70°C, respectively. The pore size distribution of ACF was also studied. It is also concluded that the final ACF strength is dependent on the concentration of impregnant.
