18.9: The Chemistry of Phosphorus
Phosphorus, when combined with aluminum or iron, becomes an insoluble salt. The solubility equilibrium constants of (FePO_4) and (AlPO_4) are 1.3x10-22 and 5.8x10-19, respectively. With solubilitys this low, the resulting precipitates can then be filtered out. Figure 1. Phosphates can lead to excessive algae growth, which can be undesirable
