-
建立了二安替比啉甲烷分光光度法测定硝酸-氢氟酸混合溶液中钛含量的分析方法,进行了精密度和加标回收率试验。试验证明,相对标准偏差均小于2.0%(n=5),加标回收率为98.33%102.14%。该方法具有较高的精密度与准确度。
- Abstract:
-
The titanium content in nitric acid-hydrofluoric acid mixed solution was determinated by diantipyrylmethane spectrophotometry. The experiments with precision and standard addition recoveries were carried out. The tests indicate that all the values of RSD’S( n = 5) are less than 2. 0% and values of standard addition recovery are in the range from 98. 33% to 102. 14%. This method has high precision and accuracy.
