应用微波消解处理酒样,不经富集直接用ICP-MS测定Cr、As、Cd、Hg、Pb含量,方法快速,干扰少.测定的33种不同酒样中Cr、As、Cd、Hg、Pb的含量均值分别为45.84、19.53、2.22、1.92 μg·kg~(-1)和115.06 μg·kg~(-1),其中白酒中含量最高,葡萄酒和啤酒居次,黄酒含量最低.Cr、As、Cd、Hg、Pb的检出限分别为0.063、0.082、0.007、0.001 μg·L~(-1)和0.080 μg·L~(-1),各元素的加标回收率基本在90%～110%,RSD(n=10)在0.25%～6.76%.

The determination method of chromium,arsenic,cadmium,mercury,and lead in alcohol samples by inductively coupled plasma mass spectrometry with microwave digestion was developed.This method was rapid,less interfered,and did not need preconcentrating.The mean contents of Cr,As,Cd,Hg,and Pb in 33 various alcohol samples were 45.84,19.53,2.22,1.92 μg·kg~(-1),and 115.06 μg·kg~(-1),respectively,among which Chinese spirits ranked as the top while Chinese rice wine as the bottom.Detection limits of Cr,As,Cd,Hg and Pb were 0.063,0.082,0.007,0.001 μg·L~(-1) and 0.080 μg·L~(-1),respectively.The recovery of the above-mentioned elements ranged from 90% to 110% while RSD (n=10) varied between 0.25% and 6.76%.
