Abstract

Developing an effective method for the detection of nitrite (NO ) ions in the natural environment especially in environmental waters and soils is very necessary, since they will cause serious damage to human health once excess NO ions enters the human body. Therefore, a new colorimetric fluorescent probe NB-NO for determining NO ions was designed, which possesses good water-solubility and satisfactory selectivity over other common ions for NO ions. The addition of NO ions changed the color of solution from blue to colorless seen by the naked-eye. Furthermore, through test and calculation, the detection limit of the probe NB-NO is 129 nM. Based on the earlier excellent characteristics, the probe NB-NO was successfully used for monitoring NO ions in environmental waters and soils.

摘要

开发一种有效的方法来检测自然环境中，特别是环境水体和土壤中的亚硝酸根（NO ）离子是非常必要的，因为一旦过量的NO 离子进入人体，它们会对人体健康造成严重损害。因此，设计了一种用于测定NO 离子的新型比色荧光探针NB-NO ，它具有良好的水溶性，并且对NO 离子的选择性优于其他常见离子。加入NO 离子后，溶液颜色肉眼可见地从蓝色变为无色。此外，通过测试和计算，探针NB-NO 的检测限为129 nM。基于上述优异特性，探针NB-NO 成功用于监测环境水体和土壤中的NO 离子。
