苏联分析工作者对铜合金中锌的测定条件作了研究、经试验确定了光电倍增管的电压、气体流量、分析线波长、狭缝宽度、空心阴极灯电流值、从燃烧器上端到光束中心的距离等最佳条件。样品用硝酸加热溶解、如有必要可加入氢氟酸和硼酸。溶液稀释后过滤、滤液中的锌用低的丙烷—丁烷(罐装 Soviet analysts analyzed the determination of zinc in copper alloys. The voltage and gas flow rates of the photomultiplier tube were analyzed. The line wavelength, slit width, and the current of the hollow cathode lamp were measured. From the upper end of the burner to the center of the beam Distance and other best conditions. Samples are heated with nitric acid to dissolve, hydrofluoric acid and boric acid, if necessary. The solution is diluted and filtered. The zinc in the filtrate is diluted with propane-butane (canned
