The equilibrium sorption of methyl orange by chitosan and its acyl (octanoyl, dodecanoyl, and octadecanoyl) derivatives was investigated. In general, a greater of substitution and a longer chain length increase the sorption of the dye; however, there are optimum degrees of substitution and chain length to enhance the sorptivity. The sorption isotherms were interpreted by means of a dual mechanism which comprises partition and Langmuir sorption modes.
