【Abstract】 Technics of refining calcium phytate was studied systematically. Acid-dissolving pH of crude calcium phytate was examined, and the dosage, the temperature, the time and the pH of active carbon adsorbing impurity were optimized. Several factors affecting the quality of product, such as neutralization pH, neutralization reagents and their concentration were investigated, and the quality of product has been improved and its cost of production has been lowered.更多还原
