摘 要 目的:建立同时测定小儿氨酚黄那敏颗粒中重金属铅(Pb)、镉(Cd)、铜(Cu)、汞(Hg)以及有害元素砷(As)含量的方法。
方法:样品经微波消解后,以锗、铟、铋元素为内标,采用电感耦合等离子体质谱法(ICP-MS)测定。结果:Pb、As、Cu、Cd、Hg元素
检测质量浓度的线性范围分别为1~20、0.5~10、5~100、0.5~10、0.2~4 ng/mL(r均大于0.997);检测限分别为0.041 1、0.013 2、
0.057 3、0.009 0、0.005 4 ng/mL,定量限分别为0.137 0、0.044 0、0.191 0、0.030 0、0.018 0 ng/mL;精密度、重复性试验的RSD均小
于6%,Pb、As、Cu、Cd元素稳定性试验(28 h)的RSD均小于5%,Hg元素稳定性试验(28 h)的RSD小于7%;平均加样回收率分别
为 89.44%(RSD=5.87%,n=9)、99.56%(RSD=5.46%,n=9)、96.12%(RSD=4.62%,n=9)、105.82%(RSD=2.80%,n=9)、
90.23%(RSD=3.59%,n=9)。63 批样品中,Pb、As、Cu、Cd、Hg 等 5 种元素均有检出,含量分别为 0.191 0~1.527 6、0.002 5~
0.047 4、0.034 1~1.549 0、0.001 5~0.078 8、0.001 9~0.005 4 mg/kg。结论:该方法操作简便、灵敏、准确,可用于同时测定小儿氨
酚黄那敏颗粒中5种元素的含量。

ABSTRACT OBJECTIVE:To establish a method for the content determination of heavy metals [lead(Pb),cadmium(Cd),
copper (Cu), mercury (Hg)] and harmful elements [arsenic (As)] in Pediatric paracetamol artificial cow-bezoar and
chlorphenamine maleate granules. METHODS:The samples were conducted pretreatment by microwave digestion instrument and
determined by inductively coupled plasma mass spectrometry(ICP-MS)using elements germanium,indium,bismuth as internal
standard. RESULTS:The linear ranges of Pb,As,Cu,Cd and Hg were 1-20,0.5-10,5-100,0.5-10 and 0.2-4 ng/mL,
respectively (all r>0.997). The limits of detection (LODs) were 0.041 1,0.013 2,0.057 3,0.009 0,0.005 4 ng/mL,
respectively. The limits of quantification(LOQs)were 0.137 0,0.044 0,0.191 0,0.030 0,0.018 0 ng/mL,respectively. RSDs of
precision and repeatability tests were all less than 6%. RSDs of stability tests(28 h)of Pb,As,Cu and Cd were all less than 5%,
and that of stability test(28 h)of Hg was less than 7%. The average recoveries were 89.44%(RSD=5.87%,n=9),99.56%
(RSD=5.46% ,n=9),96.12%(RSD=4.62% ,n=9),105.82%(RSD=2.80% ,n=9)and 90.23%(RSD=3.59% ,n=9),
respectively. Five elements were all detected in 63 batches of samples,and the contents of them were 0.191 0-1.527 6,0.002 5-
0.047 4,0.034 1-1.549 0,0.001 5-0.078 8 and 0.001 9-0.005 4 mg/kg,respectively. CONCLUSIONS:The method is simple,
sensitive and accurate. It is suitable for simultaneous determination of 5 elements in Pediatric paracetamol artificial cow-bezoar and
chlorphenamine maleate granules.
