By means of GFAAS,repeat measure the lead content of the edible cassava starch, establish the mathematical model of the Uncertainty. Systematically analyse and quantize the components of the Uncertainty , and analyse the Uncertainty in the measuring process main source in sample preparation, reference material, curve fitting and repeated test.
