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 observes 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 malachit...
