摘要
本实验利用火焰原子吸收法测定蜂蜜中的铁。测量波长2483nm，狭缝02nm，灯电流5.0mA，空气流量10．0L／min，乙炔流量2.00L／min。样品经消解或灰化（550℃）等处理后导入火焰测定吸光度，与标准系列比较定量。测得蜂蜜样品中铁含量为40．3μg／ml，RSD％＝1．29，回收率＝100．4％。
Iron in honey was detetrined by flame atothecabsorbing spectrometry method in this study.Wavelength 248. 3 nm, narrow 0. 2nm, lamp current5. 0mA, air flux 10. 0 L/min, acetylene flux 2. 00L/min. Samples were determined after being cleared up or incraerated, and were comared with standard seriet. The content of iron in honey sample is 40.3μg/ml, RSD% = 1 .29, Recovery = 100 .4%.
