WebbSubsequently, Fe and Al ions in the leachate of completely re-dissolution of Fe P and Al P in 2 N HCl were absorbed by CER to obtain a purified P solution. Over 99.0% of P in the purified P solution was recovered as struvite with a high purity (76.0%) and low heavy metal contents (Zn, Cu, As and Pb＜50 mg/kg) at a 1:1:1 M ratio of Mg: N: P and pH of 9.5. WebbpH is a logarithmic scale. A solution that has a pH of 1.0 has 10 times the [H +] as a solution with a pH of 2.0, which in turn has 10 times the [H +] as a solution with a pH of 3.0 and so forth.. Using the definition of pH, it is also possible to calculate [H +] (and [OH −]) from pH and vice versa.The general formula for determining [H +] from pH is as follows:
