Analysis of Phosphorus Soil Sorption Data: Improved Results from Global Least-Squares Fitting

Analysis of Phosphorus Soil Sorption Data: Improved Results from Global Least-Squares Fitting

Phosphate sorption data are often analyzed by least-squares fitting to the two- or three-parameter Freundlich model. The standard methods are flawed by (1) treating the measured pseudo-equilibrium concentration <i>C</i> as the independent (hence error-free) variable and (2) neglecting th...
