With most weak fluorescent emission when middle.So the present invention selected in next test ethyl alcohol as calcium-MOFs complex into
The dispersion liquid of row metal ion identification.
Calcium cooperation is detected to the recognition capability of metal ion, different metal ions (Mn will be contained2+, Al3+, Cr3+, Fe3+, Ag+Deng) ethanol solution (1mM) in be added gradually in the ethyl alcohol emulsion containing calcium-MOFs complex.As shown in figure 9, part
Ion pair calcium-MOFs complex has the effect of fluorescence enhancement, sub-fraction ion (Ni2+, Cu2+, Co2+, Pb2+, Ca2+) to calcium-
MOFs complex has faint quenching effect.When containing Mn2+And Al3+Ethanol solution when being added into, fluorescence intensity obviously increases
By force, this result shows that calcium-MOFs complex to Mn2+And Al3+There is good selectivity.
As shown in Figure 10, a small amount of Mn is being added2+When, fluorescence just has apparent enhancing, at 120 microlitres of addition containing 1mM
When the ethanol solution of Mn2+, fluorescence intensity has become original 2.25 times, and the linear growth of its reinforcing effect, illustrates calcium-
MOFs complex is to Mn2+There is good recognition effect.As shown in Figure 12, fluorescence intensity is with Al3+Increase increasing degree it is more slow
Slowly, at 300 microlitres of addition containing 1mMAl3+Ethanol solution when, fluorescence intensity has become original 1.77 times, reinforcing effect
It also is linear increase, calcium-MOFs complex is to Al3+Recognition effect be slightly worse than to Mn2+Recognition effect, but still have higher
Ion recognition character.
Pass through Stern-Volmer (SV) formula: (I0/I)=Ksv [A]+1 calculates its enhancing rate, as a result as shown in figure 14.
