According to the results of range analysis and the square of
deviation, the significance sequence of the four investigated
influencing factors was obtained and the order was as follows: the
mass ratio of carbonized material to NaOH, carbonization
temperature, activation temperature and activation time. It can
be concluded that the mass ratio of carbonized material to NaOH
has significant influences on the adsorption capacity of Cr(VI) on
LSAC and the optimal condition is A2B3C1D2 (Exp. no. 6)
