When the authors took the value of K_RP = 1, they obtained the values of normalized standard deviation (Δq) identical with those of Freundlich and Modified Freundlich for all the six isotherms. Further values of correlation co-efficient (r²) were also identical with those of modified Freundlich for all the six isotherms.

The authors have checked their calculations and by oversight instead of plotting ln[KRP(C_e/QQ_e)–1] vs. ln(C_e), equation 1, they plotted ln[K_RP(C_e/Q_e)]–1 vs. ln(C_e).

The optimum value of K_RP for the solution of the linear RP equation was found to be 1000 for all the six isotherms. Using K_RP = 1000, values of Δq were almost equal to those of the Freundlich and Modified Freundlich equations. Values of r² were also found to be better than those of the Langmuir equation and near to unity (table 1)
