Water strontium-90 rapid qualitative determination instrument

Classification

The rapid qualitative determination instrument for strontium-90 in water is an instrument for rapid qualitative determination of strontium-90 in water by the change of photosynthetic activity of planktonic algae under the stress of nuclide 90Sr. The instrument uses chlorophyll fluorescence as the probe of algae photosynthesis process to detect the photosynthetic activity of algae rapidly and nondestructively. The inhibition rate of photosynthetic activity of algae under 90Sr stress was obtained by the "control-test" dual channel test. Using the dose-effect relationship database between 90Sr and photosynthetic inhibition rate of algae, combined with the threshold model of environmental stress, rapid qualitative determination of strontium-90 in water and real-time warning of ecological and environmental risks were realized.
