In the present work, different chemical modification methods have been used to treat raw peanut shell. Characterization of different samples is carried out with SEM, FTIR and XRD. The effect of cationic dye sorption from aqueous solution by using different peanut shells has also been investigated. SEM and FTIR show that some components of raw peanut shell have been removed during the chemical modification and many cavities of various dimensions are clearly evident on the surface of modified peanut shells. Moreover, there are some especial chemical interactions between raw peanut shell and modifying agents, which lead to significant changes in the groups of raw peanut shell surface. XRD of raw peanut shell displays a typical spectrum of cellulosic material. Compared to raw peanut shell, cellulosic crystal style of modified peanut shells is not obviously changed, but the crystallinity of cellulose increased. Maximum sorption capacity of peanut shells for malachite green is obtained by modification of organic solvents (99.99 %), higher than that of raw peanut shells (80.22 %). The base treated peanut shells also enhance the malachite green sorption (94.32 %).
