FIELD: chemistry.
SUBSTANCE: transparent polymethacrylate matrix stand in the solution being analyzed by shaking for 15 minutes in a solution of NaOH solution added to parse to create a medium with pH acidity 9. Assessment of the concentration of sodium fluorescein according to the calibration schedule intensity streaks when maximum fluorescence 440 nm.
EFFECT: use of the method allows to accurately determine the sodium fluorescein in solutions.
