| Abstract: | ' By using the standard addition method,copper and lead contents in the white granulated sugar are directly and quickly determined by polarized zeeman flame atomic absorption spectrometry without the effect of referenc,background and viscosity.This method is proved as being easy,quick and highly sensitive.The relative standard deviation of copper is 0.61%-1.9% and that of lead is 0.94% ~ 3.5%.The recovery of copper is 98.4% ~ 102% and that of lead is 97.4% ~ 104%. |
