摘要: 本文研究亚硝胺与色素在光化学性质上的不同,提出了二次展开光解薄层层析法以检出粮食中的挥发性亚硝胺。 首先将亚硝胺与色素展开一定距离,然后用紫外光照射,使亚硝胺光解。当再次展开时,色素继续上升,从而使它们完全分离。

Abstract: In this paper, the difference in photochemistry properties between nitrosamine and pigments is investigated. The TLC method of twice developing light-decomposition is presented to detect the volatile nitrosamines in grain.First, nitrosamine and pigments are developed within a certain distance and, after that, the nitrosamine is decomposed under irradiation with ultraviolet light. When they are developed for the second time, the pigments keep going up and are being completely separated from nitrosamine.
