Abstract

The determination of trace elements in the Mongolian milk tea,such as Calcium,Magnesium and Zinc,was performed by flame atomic absorption spectrometry.The operation conditions were optimized.The Mongolian milk tea was treated by ashing method before determination.The results show that,there is a good linear relationship between the absorbance and concentration of trace elements.The regression equations of Calcium,Magnesium and Zinc are A=0.1334C+0.0025(R2=0.9993),A=0.4838C+0.0311(R2=0.9998),A=0.2149C+0.0224(R2=0.9997),respectively.The determination of Calcium,Magnesium and Zinc in three different Mongolian milk teas is carried out.Their RSD values are all lower than 1.25% and the recovery is around 95.0%-105.0%.
