Determination of Mineral Elements of Bee-pollen of Brassica campestris L.by Microwave Digestion-ICP-OES
摘要
Abstract
Samples were treated by wet microwave digestion procedure with HNO2/H2O2 and the mineral elements in bee-pollen of Brassica campestris L. Were completely analyzed by inductively coupled plasma optical emission spectrometer (ICP-OES). The results showed there were 17 mineral elements in the samples. The RSD of the determined values were between 0.85% and 6.97%. And RSD of the contntes of14 elements was within 5%. Standard recovery rate of 13 elements was 93.5 %-107.3 % and 9 mineral elements was within 100 %±5 %. The mass fractions of such necessary macroelements, including S, P, K, Ca, Mg and Na, were 0.74%, 0.59%, 0.35%, 0.23%, 0.13% and 0.0064%, respectively. The contents of the microelement Fe, B, Zn, Mn, Se, Cu, Sr, Ba, Ti, Si and Al were 14.3, 6.41, 2.40,1.64,1.23, 0.69, 0.54, 0.44, 0.10,50.7 and 25.8 mg/100g, respectively.关键词
