Abstract: The process of activated carbon preparation from tung shell was discussed in the presence of ZnCl2.Based on the orthogonal test,the optimal condition was obtained as follows:the ratio of tung shell to solution (w/w) is 1∶20;the mass fraction of ZnCl2 solution is 50%;the tung shell is treated for 60 min at 60  ℃.The obtained activated carbon has iodine absorption value of 986.35 mg/g,methyl blue absorption value of 178.23 mg/g and apparent density of 0.423 6 g/mL.

Key words:

tung shell, activated carbon, mass fraction of ZnCl2
