Where K2 is the rate constant of the pseudo second order adsorption (gmg-1min-1), QE and QT are the amounts of CR
adsorbed. (mg g-1) at equilibrium and at time t (min) respectively. The plot of T / Qt vs t of eqn 9 gives a linear
relationship from,, Which QE and, K2 can be determined from the slope and intercept of the plot.
