Rhodamine WT is used by surface water hydrologists for time of travel and dispersion studies in which flow characteristics of surface streams are determined. Surface water contamination by nitrosamines formed from Rhodamine WT and nitrite ion has been studied. A method for residue analysis of N-nitrosodiethylamine (NDEA) has been developed and evaluated using river samples spiked with Rhodamine WT and nitrite ion. It permits rapid and reliable determination of NDEA at a minimum concentration of 0. 03 mu g/L. The method uses solid-phase extraction and capillary gas chromatography.
