【摘要】：建立了電感耦合等離子體質(zhì)譜法(ICP-MS)混合模式測(cè)定動(dòng)植物源食品中11種痕量元素的檢測(cè)方法。樣品經(jīng)微波消解后,采用混合模式測(cè)定動(dòng)植物源食品中As,Hg,Pb,Cd,Cr,Co,Ni,Cu,Zn,Fe,M n 11種元素,內(nèi)標(biāo)法定量。結(jié)果表明:11種元素的檢出限分別在0.005~0.09μg/L之間;線性關(guān)系良好,相關(guān)系數(shù)r≥0.9995;相對(duì)標(biāo)準(zhǔn)偏差(RSD)為0.94%~7.2%;回收率在90.7%~103.5%之間;對(duì)不同食品類型的對(duì)照標(biāo)準(zhǔn)樣品GBW10016、GBW10018、GBW10044、GBW10051進(jìn)行測(cè)定,測(cè)定結(jié)果均在參考值范圍。本方法適用于批量動(dòng)植物源食品中多元素的同時(shí)測(cè)定。
[Abstract]:An inductively coupled plasma mass spectrometry (ICP-MS) method was developed for the determination of 11 trace elements in animal and plant foods. The samples were digested by microwave, and the 11 elements of As-HgHgPbPbCd-Cr-Co-NiCuZZn-FeNin in animal and plant food were determined by mixing mode and the internal standard quantity was determined. The results showed that the detection limit of the 11 elements was 0.005 ~ 0.09 渭 g / L, the linear relationship was good, the correlation coefficient was r 鈮，
