【摘要】 北京师范大学测试中心,北京100875摘要采用氢化物发生-电感耦合等离子体原子发射光谱法测定痕量锗的方法,系统地考察了不同酸介质、NaBH4浓度及共存元素的影响,确定了最佳测定条件。方法的检出限为0.2ng.mL-1,精密度为0.9%。用环境标准物质进行对照,其测定值均在给定的标准范围之内。并且针对反应介质对锗测定的影响,进行了详尽的研究。更多还原

【Abstract】 A method to determine the content of trace germanium by hydride generation inductively coupled plasma atomic emission spectrometry was established. The influences of different acidic medium, concentration of NaBH₄ and other concomitant elements are examined systemically. The optimal analytical conditions were discussed and examined. The detection limit is 0.2 ng·mL -1 and the precision is 0.9%. The value of germanium content detected in environmental reference material agrees with the certified value. The medium influence on determining trace germanium was studied in detail.更多还原
