| STUDIES ON DERIVATIVE FLUORIMETRY Ⅲ. DETERMINATION OF TRACE AMOUNT OF TERBIUM IN THE PRESENCE OF SODIUM DODECYL SULFONATE | |
| 摘 要： | The derivative fluorimetric characteristics of Tb—SDS and Tb—SDS—phenanthroline systems have been studied. The optimum conditions were obtained. The 2nd—derivative spectrofluorimetric method in the systems has been applied to the determination of trace amounts of terbium, in rare earth ore and their oxides. The results are satisfactory. |
