There is a general consensus that adsorption/desorption (i.e. sorption) is the major process controlling dissolved PO4. However, many uncertainties exist with respect to PO4 sorption capacity and properties of clay minerals as compared to Fe/Al oxides. I reviewed experimental studies performed over...
