| Abstract: | The analytical method for determination of lead and cadmium in alga food was established by inductively coupled plasma spectrometry(ICP-MS),and the analytical result was compared with that by national standard graphite furnace atomic absorption spectrometry(GFAAS).The two kinds of samples were pretreated by microwave digestion and analyzed by ICP-MS and GFAAS,respectively.The linear working curves were obtained,with the correlation coefficient above 0.9991.The precision of methods(RSD) were lower than 3.6%.... |
