B2 O3能存在于钙镁磷肥的玻璃因子网络结构中 ,采用弱酸强化可准确滴定。实践中需注意干扰离子的消除 ,强化剂的选择等因素。强碱分离电位滴定法经实践适用于规模化生产的分析检测。
B2 O3 can exist in the calcium-magnesium phosphate glass network structure factor, the use of weak acid can be accurately titrated. In practice should pay attention to the elimination of interference ions, enhancer selection and other factors. Alkali separation potentiometric titration method is suitable for large-scale production by the practice of analytical testing.
