Under three kinds of test conditions, sensor contains Cu in contact2+Substrate after output voltage decline at once, dimension
Hold output voltage under the stimulation of noxious substance to keep declining.Remove after voltage levvl is down to relatively stationary value and contain
Cu2+Substrate, remove rear sensor output voltage and go up at once, finally up to the substrate added containing noxious substance
Front voltage levvl, produces electricity and recovers required time in 30min (such as Fig. 5).
Fig. 6 is that reactor contacts Cu2+Rejection ratio curve after substrate.Reactor contact 5ppm Cu2+After,
Rejection ratio promotes rapidly, reaches 0.48 (namely output voltage reduction ratio is 48%) in 30min.And
At contact 2ppm Cu2+After, rejection ratio promotes speed than contact 5ppm Cu2+After situation slow, but 30
0.35 is still reached in min.This explanation, the sensor Cu to variable concentrations gradient2+Early warning is all had to react, reaction
It is the fastest that speed and toxic substance concentration positive correlation, i.e. concentration more high output voltage reduce speed, and amplitude is the biggest.
