WebAug 15, 2024 · 2.5. Supersaturation control. pH was selected to control the driving force of crystal growth in this work as the solubility of struvite was highly pH-dependent, and NaOH was used to adjust the acidity and alkalinity of the solution producing the supersaturation required for crystal growth. WebStruvite formation is mainly controlled by concentrations of Mg2+, NH4+ and PO4 3+, pH, temperature, and other ions like Ca2+. Experiments evaluating the effects of pH and Ca2+ on struvite formation indicated that XRD is only a qualitative method to analyze the struvite content in precipitating compounds, which was also reflected in microscopic images.
