亚硝酸根光分析方法研究的新进展

The New Progress of Determining Nitrite by Spectrology

亚硝酸根广泛存在于土壤、天然水、食品等物质中,它是水质、环境、食品等检测的一个重要项目.中国加入WTO以后,中国的农副产品要出口,克服技术贸易壁垒至关重要.因此,建立简便、快速、灵敏的亚硝酸根检测方法,在食品和环境分析中具有重要的现实意义.对亚硝酸根的光度法测定的现状及发展进行了综述.

Nitrite which exists widely in the soil, natural water and food, etc. is one of the most important indexes to test the water quality, environment quality and foodstuff quality. In order to export Chinese agricultural byproducts to the foreign countries. It has been important to overcome tradetechnology barriers, since China joined the WTO. Thus, it has practical significance to look for the simple, rapid, sensitive methods of determining nitrite. This paper summarizes the present conditions and progresses of determining nitrite.
