| Abstract:The preparation of deinking paper sludge-based activated carbon （DPS-AC） with a thin-layer and high mesopores ratio structure by using deinking paper sludge （DPS） as raw material， via twice deashing with hot water and hydrochloric acid pickling， KOH activation， and ball milling assistance was discussed in this study. The results showed that the optimal process conditions for the preparation of DPS-AC were that hot water pretreatment and acid washing treatment for two deashing， KOH solution concentration of 6.5 mol/L， solid-liquid ratio of 1∶2， carbonization temperature of 750℃， time of 90 min， and 250 r/min intermittent ball milling for 180 min. The DPS-AC prepared under these conditions had an iodine adsorption capacity of 657.50 mg/g， a methylene blue adsorption capacity of 230.69 mg/g， a specific surface area of 595.138 m2/g， a total pore volume of 0.646 cm3/g， an average pore diameter of 4.339 nm， and mesoporous well-developed structure. |
