Abstract
A sensitive approach to the determination of trace amounts of phosphate ions in aqueous solutions using surface-enhanced Raman spectroscopy on silver nanofilms modified with cetyltrimethylammonium bromide was proposed. The role of a surface modifier in enhancing the analytical signal was investigated. For pure sodium hydrogen phosphate solutions, the detection limit was 60 nM (5.7 μg/L), and the calibration function was linear over the hydrogen phosphate ion concentration range of 1 × 10–7 to 1 × 10–4 M.
期刊介绍:
The Journal of Analytical Chemistry is an international peer reviewed journal that covers theoretical and applied aspects of analytical chemistry; it informs the reader about new achievements in analytical methods, instruments and reagents. Ample space is devoted to problems arising in the analysis of vital media such as water and air. Consideration is given to the detection and determination of metal ions, anions, and various organic substances. The journal welcomes manuscripts from all countries in the English or Russian language.
