摘    要:蔬菜中亚硝酸盐、硝酸盐含量是其卫生品质的重要指标之一,研究运用格里斯试剂比色法及紫外分光光度法检测了青岛市场上冬季大棚蔬菜217个样品中亚硝酸盐、硝酸盐含量。结果表明,青岛市七区蔬菜市场上叶菜类硝酸盐污染较为严重,大部分蔬菜的亚硝酸盐处于轻、中度污染状态。研究为当地蔬菜的安全供应提供了理论依据和数据支持。

关 键 词:蔬菜  亚硝酸盐  硝酸盐  含量测定  格里斯比色法  紫外分光光度法

Abstract:Griess reagent-ultraviolet spectrophotometry method was used to determine the contents of nitrite and nitrate in 217 winter vegetable samples which sold in Qingdao. Results showed that nilrate contamination in leaf vegetables was more serious than other samples. Most samples were at the levels of light and moderate nitrite contamination. It can give theoretical basis and data support to the vegetables consumption to local residents.
Keywords:vegetables  nitrite  nitrate  content determine  griess reagent  ultraviolet spectrophotometry
