Paper Abstract

Results of the UV absorption properties of nitrate in waters and the effects of potential inorganic and organic species on these properties are presented. The attenuation of the water Raman and Rayleigh back-scattered light of appropriate wavelengths by nitrate distributed along the probed water column is correlated with nitrate concentration. An analysis of the results in terms of an extended source in the water column and integrated absorption (over a certain depth) is presented. The feasibility of using a differential absorption and scattering technique utilizing water Raman and Rayleigh back scattered signals without any optical contact with cell walls is examined, so that the problem of cell fouling in conventional absorption measurements is avoided.
