Abstract
Ultraviolet (UV) spectroscopy is an attractive detection technique for organics and other species in environmental water samples because of its potential for contactless measurement, and because of the low absorption of pure water. However, the low absolute absorptions of ppm-concentrations are difficult to resolve in the presence of high absorptions from a wide variety of benign species, such as the nitrate ion. Hence selectivity is the real problem.
