摘要: 本研究用水直接溶解蜂蜜,在选定的仪器最佳工作条件下,用火焰原子吸收法测定了天然新鲜蜂蜜与陈年蜂蜜中的锌含量。与湿法消解处理的试样相比较,该法操作简单,快速准确。加标平均回收率分别为101.5%和102.2%;相对标准偏差为2.43%和3.26%;检出限为0.8μg/ml,测定结果令人满意。

Abstract: With honey solved in water directly, on optimum conditions, the contents of zinc in fresh honey and mellow honey were determined by flame atomic absorption spectrometry. Compared with digesting sample with moisture, this method is easier, faster and accurater. It has a good recovery of 101.5% and 102.2% respectively, RSD of 2.43% and 3.26% respectively. The detection limit is 0.8 μg/ml.
