| 摘 要： | 氟的测定多采用茜素锆蒸馏比色法,费时冗长,工作效率很低。我们在桂林冶金研究所介绍的快速测定岩石中微量氟的锆一偶氮胂Ⅲ比色法的基础上进行了对黄铁矿中氟的测定。我们采用了碱半熔,氢氧化钠分离杂质,用偶氮胂Ⅲ比色测定氟,

RAPID COLORIMETRIC DETERMINATION OF FLUORIDE ION IN PYRITE |
| |
| Abstract: | The Sample was decomposed with Na2C03+KCIO3+ZnO. After extraction
with water, an aliquot portion of the solution was taken for direct colori-
metric determination, which was based on the decolorisation of the purple com-
plex formed by arsenazo III with zirconium. |
