| Abstract: | The oyster,sea mussel and yellow-fin tuna were dissolved in NaOH solution,and the five microelements contents including copper,lead,cadmium,zinc and chromium in them were determined by FAAS and GFAAS.It showed that the measured value of these elements were coincident with reference value of standard sample.The method of base-digestion to determinate five microelements oyster,sea mussel and yellow-fin tuna,were superior to the method of acid-digestion in accuracy and precision. |
