Systems and Methods for Monitoring Phenanthrene Equivalent Concentrations

摘要

The present application is directed to systems methods and methods for monitoring phenanthrene equivalent concentrations in an aqueous stream. One or more sources of electromagnetic radiation at different wavelengths may be directed into a sample of the aqueous stream and the resulting fluorescence at various wavelengths is detected. The detected fluorescence is then used to determine the phenanthrene equivalent concentration.

主权项

1. A method for measuring polycyclic aromatic hydrocarbon concentration of an aqueous stream, comprising:
passing a sample of an aqueous stream through a monitoring area; directing a first electromagnetic radiation into the monitoring area, the first electromagnetic radiation having a first wavelength; directing a second electromagnetic radiation into the monitoring area, the second electromagnetic radiation having a wavelength different than the first wavelength; monitoring at least one fluorescence when the first electromagnetic radiation is directed into the monitoring area; monitoring at least one fluorescence when the second electromagnetic radiation is directed into the monitoring area; and determining a polycyclic aromatic hydrocarbon concentration reported as a phenanthrene equivalent concentration using at least one of the monitored fluorescence.
