A Low-Power Surfatron Source for the Atomic-Emission-Spectrometric Detection of Nonmetals in Aqueous Solution

Emission spectra in the UV-visible and near-infrared (NIR) spectral regions are presented for several nonmetals introduced as aqueous solutions by a glass-frit nebulizer. Detectability improves dramatically for some nonmetals with the use of a desolvation system to reduce the amount of water vapor entering the plasma. Detection limits for P, I, S, Cl, Br, and C are in the low- to sub-ppm range. Good precision (RSD <5%) and a dynamic range of 2–3 decades were observed for I and P. Easily ionizable elements such as K, Na, and Li can enhance nonmetal emission by as much as 30%.
