Abstract

A highly sensitive and selective method for the determination of low concentrations of nitrite in aqueous solutions using surface-enhanced resonance Raman spectroscopy (SERRS) is presented. The SERRS-active substrate was silver hydrosol. In order to induce the SERRS effect, nitrite was transformed into a colored product (an azo dye) by a standard chemical reaction. The detection limit for nitrite is 0.02 nM in distilled water, and analytical calibration curves yield straight lines in the concentration range below 30 nM. The sensitivity of this method is better than that of colorimetry and other techniques such as chemiluminescence. This improvement indicates that SERRS shows great promise as a useful analytical tool for trace analysis of nitrite and dyes.
