Adsorption of methylene blue onto bamboo-based activated carbon: kinetics and equilibrium studies.
TL;DR: Two simplified kinetic models including pseudo-first-order and pseudo-second-order equation were selected to follow the adsorption processes of methylene blue and the kinetic parameters of this best-fit model were calculated and discussed.
