The conversion of wood residues into activated carbon (AC) has been considered as low-cost adsorbent with the potential to replace commercial activated carbon. However, there were few investigations on the conversion of byproducts from Mongolia oak mushroom logwood (ML) as well as Sawdust mushroom culture medium (SM) into activated carbon. Furthermore, low-cost and efficient activation methods should be researched further. The goal of this study was to produce activated carbon from two different byproducts during mushroom cultivation at 300, 500, 700°C, respectively, and evaluated their adsorption performance against arsenic. Various analysis was performed to characterize the physicochemical properties of activated carbon. The highest specific surface area of the obtained activated carbon was 1148, and 1049 m2/g for MLAC7 and SMAC7, respectively. While, the SMAC7 had a highest pore volume of 0.476 cm3/g. The results showed that the maximum removal efficiency of arsenic was 77.9% and 78.0% for MLAC7 and SMAC7. These experimental results also revealed that sawdust mushroom waste based activated carbon is a viable cheaper adsorbent for arsenic removal from wastewater.
