| Abstract: | The pepper sample treatment has been adopted by wet decomposition with HNO_3 H_2O_2.The con- tent of Fe,Zn,Mn in pepper is determined by atomic absorption spectrometry(FAAS).Through screening for many times,the best work condition of treatment is assured at last.The method is simple,precise and sensi- tive with the relative standard deviation of 1.9-3.3% and the recoveries of 86.52-94.45%. |
