Ca(II) imprinted chitosan microspheres: An effective and green adsorbent for the removal of Cu(II), Cd(II) and Pb(II) from aqueous solutions (2014, background): “Considering the last step is the rate-determining step, Azizan carried out a theoretical analysis on adsorption kinetics [24] and found that the general equation could convert to either a pseudo-first-order model at high initial concentration of solute or a pseudo-second-order model at short contact”
Mathematically modeling fixed-bed adsorption in aqueous systems (2013, positive): “Certainly, we can obtain a linear form of the Langmuir model e e e m m 1 , C C q q b q (5) where a d/ ,b k k (6) where ka refers to the adsorption rate coefficient of the Langmuir kinetic model, and kd is the desorption rate coefficient (Azizian, 2004).”
Implications of apparent pseudo-second-order adsorption kinetics onto cellulosic materials: A review (2019, methodology): “However, the results of most adsorption studies are determined based on measured changes in the bulk concentration (Azizian 2004; Hubbe et al. 2012a).”
