Evaluation of some fluorescent dyes for water tracing
Eight fluorescent dyes were compared in the laboratory and in field experiments to assess their utility in quantitative tracing work. The properties considered included sensitivity and minimum detectability, the effect of water chemistry on dye fluorescence, photochemical and biological decay rates, adsorption losses on equipment and sediments, toxicity to man and aquatic organisms, and cost. Orange dyes are more useful than blue or green because of the lower background fluorescence at the orange wave band, which permits higher sensitivities to be obtained. Of the tracer dyes examined, rhodamine WT (orange), lissamine FF (green) and amino G acid (blue) are the three recommended; they may be used simultaneously to trace three injection sites with the given combinations suggested.
