Adsorption Behavior of Malachite Green from Aqueous Solution onto Bamboo Leaves Biomass

摘要

The native bamboo leaves biomass was investigated systematically as biosorbent for adsorption of malachite green from aqueous solution. The results show that the rapid malachite green absorption in aqueous solution by bamboo leaves biomass at pH 6 at ambient temperature obseraes the pseudo-second order reaction kinetics. The absorption isothermal behavior could be dissected well by Langmuir absorption isothermal, indicative of malachite green adsorbed in homogeneous surface of bamboo leaves biomass. The monolayer adsorption process for malachite green adsorption by bamboo leaves biomass and adsorption of each malachite green molecule with equal activation energy. This might be attributed to the unique morphology and composition of bamboo leaves biomass.
