However, in most previous studies, the concentration of condensed P species in solution was determined using colourimetry, with the polyphosphate concentration calculated as the difference between total P and initial OR Due to the digestion procedure required to determine total P, some weakly adsorbed and organic P species would be included in the solution P measurement, resulting in an underestimation of P sorption.
