磷钼蓝法测定磷酸锌中的磷含量

Determination of Phosphorus in Zinc Phosphate with Molybdenum-blue Spectrophotometry

摘要: 通过钼蓝分光光度法与磷钼酸喹啉重量法测定磷酸锌中磷含量的比较,说明钼蓝法测磷具有快速、方便的优点,但需注意温度和干扰离子的影响.

Abstract: The comparison of experiment parameters were conducted between Molybdenum-blue spectrophotometry and phospho-molybdic quinoline gravimetric methed in determination for phosphorus of Zinc phosphate.The results showed the former is both quick and convenient.But temperature and disturbing (ions) would influence colour reaction.
