摘要

In this study, rice husks (RHs), an agriculture by-product, were used as precursor for the production of activated carbon by chemical activation with ZnCl_2-CuCl_2 composite activator. The effect of process variables, such as ZnCl_2 concentration, CuCl_2 concentration, activation temperature, and activation time, were investigated. The optimal process condition was obtained through orthogonal test. Then the morphology, pore structure, and surface chemistry of rice husk-based activated carbon (RAC) were analyzed. When using 5 mol/L ZnCl_2 and 0.4 mol/L CuCl_2 at the carbonization temperature of 500℃ for 1.5 h, the BET surface area of the produced activated carbon was as high as 1924 m~2/g and the total pole volume reached 1.493 cm~3/g. The surface area was strongly affected by ZnCl_2 concentration and the subsequent activation temperature. RAC prepared under the optimum conditions had remarkable adsorptive properties and notable treatment effect for fuchsine.
