摘要
在不具备大型仪器的实验室,硅酸盐岩石中五氧化二磷测定方法主要有磷钒钼黄光度法、磷钼蓝光度法[1-3]和锑盐钼蓝光度法[4],前二均已被列为国家标准方法(GB/T 14506.9-93).本文通过对比三种方法的实验操作繁简、用时长短、试剂配制用量、结果的准确度和精密度[5],得出最适用于测定五氧化二磷的检验方法.综合分析,锑盐钼蓝光度法是更为操作简便、准确、实用的方法,能更好地满足样品的检验需求.
Abstract
In the laboratory without large-scale instruments,the main methods for the determination of phosphorus pentoxide in silicate rocks are phosphorus vanadium molybdenum yellow spectrophotometry,phosphorus molybdenum blue light method,and antimony salt molybdenum blue light method,the first two have been listed as the national standard method(GB/T 14506.9-93).In this paper,the most suitable test method for the determination of phosphorus pentoxide was obtained by comparing the three methods of simple operation,time,reagent dosage,accuracy and precision of the results[5].Synthetical analysis,antimony salt molybdenum blu-ray method is a more simple,accurate and practical method,which can better meet the needs of sample inspection.
