| 摘 要： | 本文提出一种测定金属铯中痕量磷、砷的方法──孔雀绿离子对试剂分离、间接原子吸收测定法。该离子对是由孔雀绿和磷（砷）酸钼生成薄膜，介于水相和乙醚相之间。分离后，用甲醇溶解，并用原子吸收法测定钼来确定磷、砷的含量。

| Abstract: | A method of floatation-and-extraction indirect AAS for measuring P and As in pure cesium is proposed. Malachite green is used as an ion-pairs reagent, and the ion-pairs of malachite green with molybdophosphate (molybdoarsenic) is floated as a membrane-like substance at the phase boundary between aqueous phase and diethyl ether phase. After seperation it is dissolved by methanol. The trace P and As are then determined by AAS. The recoveries are 95-103% for P and 99-100% for As, respectively. The RSDs are 4.5-6.3% for P and 4.6-9.2% for As, respectively. |
