摘要
运用微波消解-电感耦合等离子发射光谱(ICP-AES)技术,建立蜂蜜中重金属元素的测定方法。测定了蜂蜜中的钡、铜、铅、镉、砷、汞、铬、锰等8种重金属的含量,各元素在0~10.0 mg/L测定线性范围内,呈良好线性关系,相关系数均在0.999以上,加标回收率为94.1%~110%,测定结果良好。与常规分析方法相比,该法简便、快速、可靠,应用于蜂蜜中多元素的测定。
In order to build method for measuring of elements in honey, the contents of Ba, Cu, Pb, Cd, As, Hg, Cr, Mn, Se had been determined by microwave diges- tion (MWD) and actively coupled plasma atomic emission spectrometry (ICP-AES). The results show that, the range of heavy metal elements were in the range of 0- 10.0 mg/L, with good linear relationship. In addition, all correlation coefficients kept higher than 0.999, and the recovery rate of ample added with standard solution was in 94.1%-110%. By comparison with the result of chemical experiment, the method was quickly accessible and convenient, widely used in the measurement of elements in honey, with satisfactory results.
