Abstract
Inductively Coupled Plasma Optical Emission Spectrometer(ICP-OES)was proposed to determine of 6 elements including iron,calci-um,aluminum,lead,zinc and arsenic in food additives by directly introduction under method of organic phase.With ethanol solution as a diluent,the samples are directly analyzed after being diluted according to a specific ratio,the results showed that good linearity in the concentration range of 0.05-5.00 mg/L and the correlation coefficient was over 0.9999,the limits of detection(LODs)of all the elements were in the range from 0.0001-0.0016 mg/L,the average recoveries were 91.4％-108.4％,and the relative standard deviations(RSD)were 0.53％-3.65％.This method is simple to operate,highly accurate,safe and fast.It can be used for detecting impurity elements in compound food additives.关键词
