2、品,用电感耦合等离子体原子发射光谱(ICP-AES)法同时分析毛皮动物貉的被毛组织中多种微量元素.Ba,Be,Cd,Si,Y,Zn的测定下限为1.0～9.0ng/g级,B,Fe,La,Mg,Mo,Ni,Ti,Co,Cr,Cu,Sr,V,Zr的测定下限为0.01～0.09μg/g级,In,Th,P,Pb的测定下限为0.13～0.23μg/g级,Nb为1.08μg/g级.经国家人发标准物质(GBW07601)验证,测得该方法相对误差为0.83%～9.59%,相对标准偏差为0.81%～5.20%,各项检测指标均能满足生物样品检测要求.分别测得健康种貉、自咬症轻重病
3、貉被毛中的22种微量元素,健康貉的B,Co,Cr,Ni微量元素含量明显高于病貉,而Al,Ba,Be,Cd,Mo,Pb,Sr,Ti,Zr元素含量较低.关键词:貉;被毛组织;电感耦合等离子体原子发射光谱;微量元素中图分类号:O657.31文献标识码:A文章编号:1671-5489(2008)05-0988-04AnalysisofTraceElementsinFurofNyctereutesbyICP-AES1234WANGSong-jun,WANGPu-jun,CHANGPing,HOUTian-ping(1.CollegeofChemistryandBioe
