【摘要】 采用微波消解-端视等离子体发射光谱(ICP-AES)测定蜂产品中重金属微量元素铅、镉、砷,并对ICP-AES工作参数及条件进行了优化和选择,Pb、Cd、As的检出限分别为2.9×10-3mg/L、0.056×10-3mg/L、5.2×10-3mg/L,线性范围为0～500μg/L,相对标准偏差范围为2.9%～8.5%;回收率范围为91%～102%。该方法与国标法比较,结果无显著性差异,能满足蜂产品测定要求。更多还原

【Abstract】 A method of microwave digestion axial-view ICP-AES was applied to determine heave metals trace elements lead,arseic,cadmium in honey products. Operation parameters of ICP-AES and condition were optimized and selected. The detection limit was Pb:2.9×103 mg/L,As:5.2×103 mg/L,Cd:0.056×103 mg/L.The RSD was in the range of 2.9 %-8.5 % and the recovery was in the range of 91 %~102 %.This method was compared with the national standard way and their resultes showed no significant difference from that of the national standard way .The resulte was satisfactory for honey products.更多还原
