WebJul 10, 2024 · The pH shift was measured upon cooling the solutions from 20 to −25 °C. When the buffer concentration was 100 mM, cooling caused a pH decrease of 3.1 and 2.7 units (for BSA and β-gal, respectively) attributed to selective crystallization of disodium hydrogen phosphate as a dodecahydrate. 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.
