标准范围

该方法包括在水解(如有必要)后,在约75°C的酸性介质中,在丙酮存在下沉淀以喹啉磷钼酸盐形式存在的正磷酸盐离子,然后过滤、洗涤、干燥并称量所得沉淀物。

The method consists in precipitating, after hydrolysis if necessary, of orthophosphate ions in the form of quinoline phosphomolybdate, in an acid medium and in the presence of acetone, at approximately 75 °C, followed by filtrating, washing drying and weighing of the precipitate obtained.
