标准摘要
[中文适用范围]： 该方法在于，如果需要，在水解后，在酸性介质中并在丙酮存在下，在约75℃下以喹啉磷钼酸盐的形式沉淀正磷酸根离子，然后过滤、洗涤、干燥并称重所获得的沉淀物。 [外文原描述]： 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.
