Experimental determination of struvite dissolution and precipitation rates as a function of pH

► Struvite was dissolved and precipitated in closed-system reactors. ► Experiments were performed at 25 °C and 7.76 < pH < 10.65. ► Aqueous fluids rapidly equilibrate with struvite. ► Struvite solubilities and dissolution and precipitation rates were retrieved. ► Results support use of struvite as a renewable fertilizer.
