Abstract

This paper describes a simple method for the determination of 28 micro-elements including Ag,Cd,Cs,Ba,Li,Be,Na,Mg,Al,K,Ca,V,Cr,Mn,Fe,Co,Ni,Cu,Zn,Ga,As,Se,Tl,Pb,Bi,U,Rb,and Sr in Chinese liquor by using inductively coupled plasma mass spectrometry(ICP-MS).For digestion of samples,10 mL of a mixture of HNO3 with HClO4(4:1,V/V) was used.The results revealed that the method had some advantages,such as simple sample pretreatment,fast analysis,low detection limit,high precision and accuracy,and wide linear dynamic range(0–300 μg/L for 21 of these micro-elements,0–30 μg/L for the rest).The recovery rates for all the micro-elements were between 85.19% and 104.01% with RSD less than 4.7%.This method can completely meet the requirements for determination of the 28 micro-elements in Chinese liquor.
