摘　　要：建立了石墨炉原子吸收分光光度法测定奶粉中锰的方法并用于实际样品的测定，结果：回收率为93．9％-105．8％，RSD为1．24％-2．06％。In this paper ,we discuss and set up the suitable operating conditions for determination of Mn in milk powder by graphite furnace atomic absorption spectrometry. The method was simple, both the precision and sensitivity were high. RSD was 1.24 %-2.06 %, the recovery was 93.9 %-105.8 %.
