Table 1 Regression coefficients (R2), equilibrium adsorption capacities (\({\mathrm{q}}_{\mathrm{e}}\)) of MB (mg/g) and the rate constants (\({\mathrm{k}}_{1}\)) of the PFO kinetics model as obtained from the regression of Fig. 3A using the exponential equation: \({\mathrm{q}}_{\mathrm{t}}={\mathrm{q}}_{\mathrm{e}}\left[1-\mathrm{exp}\left(-{\mathrm{k}}_{1}\mathrm{t}\right)\right]\).
