A Simple Fluorescence sensor for detecting of Nitrite (NO2-) in Real Samples using Water-dispersible Graphite-like Carbon Nitride (w-g-C3N4) Nanomaterials

Abstract

A novel strategy was developed for fluorescence detection of nitrite (NO2-) in real samples. The method based on the reaction of water-dispersible graphite-like carbon nitride (w-g-C3N4) against nitrite (NO2-) in an acidic medium to form a new kind of weak fluorescence species. Under optimal conditions, the limit of detection (LOD) for nitrite (NO2-) detection was determined to be 0.16nM (S/N=3), and the relative fluorescence intensity showed good linearity versus logarithm concentration of nitrite (NO2-) in the range of 0 to 58.5uM with R2=0.997. This probe displayed several appealing properties, including low cost, simplicity and convenience, high sensitivity, and excellent selectivity.
