以新癀片为对象采用同一的微波、酸消解法，用还原气化冷原子荧光法测汞；用氢化发生-电感耦合等离子体原子发射光谱法测砷；用石墨炉原子吸收法测铅和铜。并用加际消化和国家标准物质的测定，证明方法准确可靠。
The same microwave and acid digestion method was used for the new bismuth films. Mercury was measured by reducing gasification cold atomic fluorescence spectrometry; arsenic was detected by hydrogenation generation-inductively coupled plasma atomic emission spectrometry; and the lead was determined by graphite furnace atomic absorption spectrometry. copper. With the addition of digestion and the determination of national standard materials, it is proved that the method is accurate and reliable.
