电感耦合等离子体-质谱法测定陈醋中14种微量金属元素
Determination of Fourteen Trace Metal Elements in Mature Vinegar by Inductively Coupled Plasma Mass Spectrometry（ICP-MS）
摘要
Abstract
A method for the simultaneous determination of 14 trace elements（Al,Cr,Fe,Co,Cd,Mn,Cu,Zn,Ni,As,Se,Sn,Sb and Pb） in Chinese mature vinegar was developed by microwave digestion followed by inductively coupled plasma mass spectrometry（ICP-MS）.The best results for the recovery of the analytes were obtained employing a digestion system composed of 7 mL of nitric acid and 1 mL of hydrogen peroxide.Good linear relationship was found for all the elements（r ≥ 0.999）.The detection limits of the method ranged from 0.003 mg/L to 1.035 mg/L.The average recoveries were 80.03%-121.13%,with a relative standard deviation of 1.68%-16.78%.Significant differences in the content of each trace element were found among three commercial vinegar samples packaged with plastic,glass and ceramic materials,respectively.关键词
