灰化后的样品用硝酸—氢氟酸—高氯酸—磷酸分解后,在磷酸(1+4)溶液中,以5%的盐酸水溶液为载流,锗与硼氢化钾反应生成氢化物气体,以氩气为载气导入电热石英炉,火焰中的氢基与氢化物碰撞解离成自由原子,以锗的高强度空心阴极灯作光源,在原子荧光光度计上测量锗的荧光强度,根据原子荧光强度的高低可测得试料中锗的含量。
The ashed sample was decomposed with nitric acid-hydrofluoric acid-perchloric acid-phosphoric acid and then carried out with a 5% aqueous solution of hydrochloric acid in phosphoric acid (1 + 4) solution and germanium reacted with potassium borohydride to form a hydride gas , Argon gas as a carrier gas into the quartz furnace, the flame of the hydrogen radical and hydride collision dissociation into free atoms to germanium high-intensity hollow cathode lamp as a light source in the atomic fluorescence spectrophotometer to measure the fluorescence intensity of germanium, According to the level of atomic fluorescence intensity can be measured in the sample of germanium content.
