Crystallization in ph probe
WebAug 1, 2024 · A pH-meter probe was immersed in the reaction medium in order to check the pH regularly. The study of struvite crystallization was carried out for variable initial pH values of 8.5, 8.7, 9.6, 10.5 and 11.8 at constant temperature. Temperature was regulated by using a thermostatized water bath maintained at 25 °C.
