采用HNO_3-H_2O_2消解体系对薰衣草花穗进行程序升温微波消解制样,应用火焰原子吸收光谱法测定了蘸衣草花穗中的金属元素Ca、K、Mn、Zn、Mg、Fe、Cu、Na、Sr等的含量。对样品前处理方法、酸度、共存元素干扰及元素线性范围进行了实验条件的筛选,在选定的最佳实验条件下,确定了合适的样品微波消解体系并做了消解结果的准确度和精密度实验,该方法的加标回收率为90.0%—104.0%,相对标准偏差RSD≤2.37%。实验结果表明新疆薰衣草花穗中富含Ca、Mg、K、Na等对人体有益的金属元素,而Sr、Cu的含量较低。 The flower buds of lavender were subjected to microwave digestion with HNO_3-H_2O_2 digestion system. The contents of Ca, K, Mn, Zn, Mg, Fe, Cu and Na in the flower spikes were determined by flame atomic absorption spectrometry Sr and other content. The sample pretreatment method, acidity, coexisting element interference and elemental linear range were selected for the experimental conditions. Under the selected optimal experimental conditions, the suitable sample microwave digestion system was determined and the accuracy and precision of digestion results were determined Degree experiments, the method of spiked recovery was 90.0% -104.0%, the relative standard deviation RSD ≤ 2.37%. The experimental results show that Xinjiang lavender spikes are rich in metal elements beneficial to human body such as Ca, Mg, K, Na, while the content of Sr and Cu is relatively low.
