| Abstract: | it is introduced in this paper that using an extracting system of patassium iodide-methyl isobuty ketone,trace cadmium in pectin is richened.The organic phase is in-troduccd into airacetylene flame directly then atomic absorption spectrometry(AAS)is applied.The higher sensitivity have been obtained and the results of method are significantly. |
