Five Parameter Isotherm Analysis
A five-parameter empirical model that is capable of simulating the model variations that applies over a wide range of equilibrium data. Its increased parameters provides a more accurate non linear regression, better than two, three or four parameters. (Subramanyam and Ashutosh, 2009)
