CHANGE IN THE INTENSITY OF THE WATER FLUO RESCENCE EVOKED BY ORGANIC-MATTER TRANSITION FROM A SUSPENDED STATE INTO THE SOLUTION

In the context of earlier developed notions for absorption spectra the correlation between intensity of flurescence of suspended matter and the solution is obtained. A model on whose basis this was done involve s the consideration of absorption of exciting radiation and reabsorpti on of the fluorescence emission by a suspended matter particle. The fo rm of the suspended matter particle was approximated by a sphere. It i s shown that the difference between the intensity of the Suspended mat ter fluorescence and that of the solution caused by the effect conside red are determined by the particle dimensions and their absorption coe fficient. The quantitative estimation of these differences is consider ed on the example of phytoplankton in the water. It is shown that in t his case the fluorescence intensity under the conditions of the fluore scent matter transformation from a suspended state into solution may a ugment by several times and exceeds considerably corresponding variati ons in the absorption spectra.
