In this study, synthetic viscose rayon fabric has been used for preparing activated carbonfabric (ACF), impregnated with different concentrations of H3PO4. The effect of H3PO4 impregnationon the weight yield, surface area, pore volume, chemical composition and morphologyof ACF were studied. Experimental results revealed that both Brunauer-Emmett-Teller surface area and micropore volume increased with increasing H3PO4 concentration;however, the weight yield and microporosity (%) decreased. It was observed that samplesimpregnated at 70°C (AC-70) give higher yield and higher microporosity as compared to30°C (AC-30). The average pore size of the ACF also gradually increases from 18.2 to 19and 16.7 to 20.4 ? for 30°C and 70°C, respectively. The pore size distribution of ACF wasalso studied. It is also concluded that the final ACF strength is dependent on the concentrationof impregnant.영어 초록
