  • Metal ion detection equipment and metal ion detection method
    Patent number: 10557795
    Abstract: A metal ion detection equipment and a metal ion detection method are provided. The metal ion detection equipment includes a porous silicon resonant cavity structure, an electrochemical device and a spectrum detecting device. A sample solution permeates into the porous silicon resonant cavity structure. A to-be-detected metal ion of the sample solution in the porous silicon resonant cavity structure is reduced into a to-be-detected metal by the electrochemical device. The spectrum detecting device detects a spectral variation of a reflective light from the porous silicon resonant cavity structure.
    Type: Grant
