| 中文摘要: |
| 500℃时在锌粉、氯化铵存在下，锑以三氯化锑形式被挥发除去，锡与锌形成锌-锡合金留在残渣中，从而消除锑对锡的干扰。在10％(体积分数)的盐酸介质中，硼氢化钾将锡（Ⅱ）还原成四氢化锡，用氢化物发生-原子荧光光谱法测定锡的荧光强度。方法检出限为0.20 mg/kg，精密度（RSD，n＝7）为3.73%，回收率为91.0％～104.5％。 |
| 英文摘要: |
| A method for the determination of tin in antimory trioxide by hydride generation atomic fluorescence spectrometry was proposed, which base on the Sn (Ⅱ) reduced to SnH4 by potassium borohydride in the media of 10% hydrochloric acid. At 500℃ and in the existence of ammonium chloride and zinc, antimony was transformed to volatile antimony trichloride and them removed. Tin and zinc was formed to zinc tin alloy and remained in the residue, so as to eliminate the interference of antimony on the determination of tin. The detection limit of the method for tin is 0.20 mg/kg and recovery is 91.0％～104.5% with precision of 3.73%RSD (n=7). |
