ICP-MS法测定蜂花粉中的微量元素含量
Application Study on Determination of Trace Elements in Bee Pollens by Inductively Coupled Plasma Mass Spectrometry
摘要
Abstract
A method was established to determination of Na, Mg, Al, K, Ca, Cr, Mn, Fe, Cu, Zn, Co, Ni, As, Se, Sr, Mo, Cd, Sb, Ba and Pb in bee pollens. After microwave digestion, the samples were determined directly by inductively coupled plasma mass spectrometry. Under the optimal conditions, the calibration curves for 21 trace elements were linear in the range of 0-10 μg/mL with correlation coefficients more than 0. 999. The quantization limit of the method were ranged from 0.029 ng/g to 148.3 ng/g with RSD of 0.6%~4.6% (n=6). The mean recoveries of 21 trace elements from spiked samples at the spiking levels of 0.002-3000 μ/g were ranged from 91.7% to 110%. Results showed that the 21 trace elements values detected were in good agreement with the corresponding certified reference values inbee pollen (GSB-17), the degree of consistency were 91.2% to 115.3%. The proposed method is fast, simple, sensitive and accurate, which can meet the demand for determining 21 trace elements in bee pollens.关键词
