Abstract:
The adsorption performanee of pyrolytie carbon from riee husk modified with CaCl, soaking and mi.erowave heated method for aniline from aqueous solution was studied. The experimental results showed thamodified pyrolytie carbon ( MW.PC) exhibited larger adsorption eapacities than unmodified pyrolytie carbon(PC) for aniline. "The adsorplion isotherm of aniline followed the Langmuir model and the maximum adsorption capaeity was 0.623 mmol/g at 298K. The adsorplion of aniline was a process of spontaneity, enthalpy in.erease and enlropy inerease. The experimental data followed the pseudo-second-order kinetie model. The besdesorption reagent for saturated MW.PC with aniline was absolute ethyl aleohol.
