微波法测定面制食品中的铝含量

Aluminum Content in Wheat Flour Food Determined by Microwave Method

铝广泛的存在于食品中,特别是面制食品。而铝是一种具有特殊生物毒性的致毒因子,所以,铝含量的测定对于人们生活质量有着重要意义。着重研究一种新的样品消解方法——微波溶样,得出微波溶样过程的最佳条件,经实验对比,此法不仅方便、快捷、操作安全、对环境污染小、可以同时消解十几个样品,而且有着满意的准确度和灵敏度。

The aluminum consists widely in food, especially in wheat flour food. But the aluminum is an intoxicating factor with special bio-toxicity, thus, the determination of aluminum content is very important for quality of life. The optimum condition of Sample microwave digestion can be obtained by studying emphatically a new sample digestion method -sample microwave digestion, compared with experimentation, this method not only has the advantages of convenient, quick and safe operation, low pollution to environment, and ably to digest simultaneously over ten samples, but also has the satisfactory accuracy and sensitivity.
