茴油是我区名贵的土特产之一。经济价值比较高,用途广泛,在国内外都是畅销的商品、常用于食品调味、饮料、医药、香料工业等方面。目前国际上对食品及其添加剂的卫生条件要求越来越高,商品在生产、包装、储运过程中可能产生的污染。已经引起各国卫生组织的广泛重视。考虑茴油的性质、生产、包装、储存和用途等因素,我们对库存的茴油进行一次锌、铜、铁含量的测定和调试。并对这些元素用原子吸收法和化学比色法进行对比试验。从所得的结果看两种方法的数值是接近的;但从提高工作效率、缩短时问、经济核算采说,原子吸收法就比化学法优越,它不但可提高工作效率,减少开支,在方法上也能减免因加入各种化学试剂可能引起对测定元素的干扰,从我们进行原子吸收法测定和加入已知量回 Fennel oil is one of my favorite local products. Economic value is relatively high, a wide range of uses, are popular at home and abroad are commodities, commonly used in food seasoning, beverages, medicine, spices industry and so on. At present, the international sanitary requirements on food and its additives are getting higher and higher, and the pollution that may occur in the process of production, packaging, storage and transportation of commodities. It has drawn wide attention from WHO. Taking into account the nature of fennel oil, production, packaging, storage and use and other factors, we conducted an inventory of fennel oil zinc, copper, iron content determination and debugging. And these elements by atomic absorption and chemical colorimetric contrast test. The results from the two methods are close to the value; but to improve work efficiency, shorten the time to ask, economic accounting mining said that atomic absorption method is superior to chemical method, which not only can improve work efficiency and reduce costs, in the method Can also be reduced due to the addition of various chemical reagents may cause interference on the determination of elements from our atomic absorption spectrophotometry and determination of the known amount of back
