| Abstract: | Mercuric ion selective PVC membrane electrodes based on eight thiacrown ethers wereprepared and their electrode behavior was evaluated. These electrodes exhibited a linear res-ponse to the mercuric ion within the concentration range of 10~(-6)-10~(-3)mol/L Hg(NO_3)_2with slope of 45-58mV per decade. The lowest limit of linear response extended to 10~(-6)mol/L. |
