Embodiment 1

[0028] At a concentration of 1.0 x 10 -5 mol / L iridium-phthalocyanine metal complex THF solution, add 0.1 times the equivalent of AgBF 4 , so that the silver ion is 0.1 times the equivalent of the iridium-phthalocyanine metal complex, A 690 / A 814 Reduced from 1.15 to 1.13.

Embodiment 2

[0030] At a concentration of 1.0 x 10 -5 mol / L iridium-phthalocyanine metal complex THF solution, add 0.1 times the equivalent of AgBF 4 , so that the silver ion is 0.2 times the equivalent of the iridium-phthalocyanine metal complex, A 690 / A 814 Increased from 1.13 to 1.15

Embodiment 3

[0032] At a concentration of 1.0 x 10 -5 mol / L iridium-phthalocyanine metal complex THF solution, add 0.1 times the equivalent of AgBF 4 , so that the silver ion is 0.3 times the equivalent of the iridium-phthalocyanine metal complex, A 690 / A 814 Reduced from 1.15 to 1.13

Abstract

The invention relates to application of a phthalocyanine-iridium metal complex to detection of silver ions. The phthalocyanine-iridium metal complex is dissolved in tetrahydrofuran or dichloromethane; then a to-be-detected substance is gradually added; an absorption spectrum is detected; and if the ratio A690 / A814 (i.e., the absorbance value of the complex at 690 nm to the absorbance value of the complex at 814 nm) of the phthalocyanine-iridium metal complex changes, it is proved that the to-be-detected substance contains silver ions, or otherwise, the to-be-detected substance does not contain silver ions. Compared with the prior art, the application provided by the invention has the advantages of rapidness in implementation, accuracy, low cost, high selectivity, etc.

Description

technical field [0001] The invention relates to the technical field of chemical sensors, in particular to a phthalocyanine-iridium metal complex and its preparation and application. Background technique [0002] Silver ions are widely used in the chemical field. Silver ions have a bactericidal effect. Silver ions penetrate the cell membrane wall and enter the cell, and react with sulfhydryl (-SH), causing protein coagulation, destroying the activity of cell synthesis enzymes, and cell division and proliferation. ability to die. When the bacterium loses its activity, it becomes neutral, and the silver ions dissociate and then combine with the bacteria to sterilize, so as to achieve a long-lasting antibacterial effect. Silver is a broad-spectrum antibacterial metal, and a small amount of silver ions has a good antibacterial effect. Modern research has further proved that as long as a certain amount of silver is dissolved in water and turned into silver ions, it will have a s...
