标准摘要
[中文适用范围]: 基于测试部分在盐酸存在下长时间沸腾而发生的水解。 在丙酮存在下,磷酸根离子以喹啉磷钼酸盐的形式沉淀。 通过过滤坩埚过滤、洗涤、干燥并称重沉淀物。 [外文原描述]: Based on hydrolysis of a test portion by prolonged boiling in the presence of hydrochloric acid. Precipitation of the phosphate ions in the form of quinoline phosphomolybdate in the presence of acetone. Filtration by means of a filter crucible, washing, drying and weighing of the precipitate.
英文名称Sodium tripolyphosphate and sodium pyrophosphate for industrial use — Determination of total phosphorus(V) oxide content — Quinoline phosphomolybdate gravimetric method
