摘要
以硫杂冠醚为活性物质的PVC膜汞(Ⅱ)离子选择电极的研究近年已有报道,我们曾报道二茂铁硫杀冠醚PVC膜汞(Ⅱ)离子选择电极的研制。并根据硫和汞的软硬酸碱相亲性,设计并合成了8个新型硫杂冠醚。本文以它们为活性物质研制PVC膜汞(Ⅱ)
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.
