| Abstract: | The wine sample was digested by hydrochloric acid and HNO3.The metals as Cu,Zn,Fe,Mn,Pb and Cd were determinated by atomic absorption spectrometry continuously.Good linear,high sensitivity,low detection limit,were obtainted with less interference.The method recovery was 93.5%—103.6%.The relative standard deviation was less than 5.0%,with satisfactory results.The method is rapid,simple and its sensitivity and accuracy can meet requirement of intermediate products in the enterprise. |
