日本研究了用直接雾化原子吸收光谱法测定硅酸盐岩矿中的锂、铍、钴、镍、铜、铷、铯、铅和铋的最佳实验条件。把每份1.0mg的粉状样品(粒度为0.3—25μm)与同量石墨粉混合,并按照已确定的加热程序置于石墨炉中的微型石墨杯内雾化。用标准水溶液进行校准,在这种溶液中,若要测定Rb和Cs,则要加入500ng钾作电离缓冲剂。 Japan studied the best experimental conditions for the determination of lithium, beryllium, cobalt, nickel, copper, rubidium, cesium, lead and bismuth in silicate rock by direct atomization atomic absorption spectrometry. Each 1.0 mg powdered sample (0.3-25 μm particle size) was mixed with the same amount of graphite powder and atomized in a micro-graphite cup placed in a graphite furnace according to the established heating schedule. Calibrate with standard aqueous solutions in which 500 ng of potassium is added as an ionization buffer to determine Rb and Cs.
