报道了以PVG-双硫腙（DTZ）-Cu（Ⅱ），PVC-DTZ-Cu（Ⅰ）为载体制备了性能良好的SCN-离子电极，其选择性次序为SCN~-》ClO_4~->Sal~-》NO_3~-~Cl~->PO_4~(2-)。16℃时，膜组成为PVC－DTZ-Cu（Ⅰ）：PVC：邻硝基苯基辛醚（o-NPOE）＝12∶22∶66的SCN~-离子电极，在0．02mol/LHCl体系中，在1×10~(-2)~5×10~(－6)mol/LSCN~-浓度范围呈能斯特响应，斜率为58±2mV/dec,检测限为2×10~(-6)mol/L；膜组成为PVC-DTZ-Cu（Ⅱ）∶PVC∶o-NPOE∶四苯硼酸钾（KTPB）为8∶22∶55∶15的电极，在0．01mol/LHAc-NaAc缓冲体系中，在10~(-2)~2×10~(-6)mol/LSCN~-浓度范围呈线性响应，斜率为54∶1mV/dec，检测限为8×10~(－7)mol/L.研究了阴离子与载体作用的机理，表明SCN~-与载体中铜原子直接作用。电极应用于废水中SCN~-的测定，结果令人满意。
Reported that SCN- ion electrodes with good performance were prepared by using PVG-dithizone (DTZ) -Cu (Ⅱ) and PVC-DTZ-Cu (Ⅰ) as carriers. The selectivity order was SCN ~ - “ClO_4 ~ -> Sal ~ - ”NO_3 ~ - ~ Cl ~ -> PO_4 ~ (2-). At 16 ℃, the membrane composition was SCN ~ - ion electrode with PVC-DTZ-Cu (Ⅰ): PVC: o-NPOE = , The Nernst response was in the range of 1 × 10 ~ (-2) ~ 5 × 10 ~ (-6) mol / LSCN ~ - with the slope of 58 ± 2mV / dec and the detection limit of 2 × 10 ~ (- 6) mol / L; the membrane was composed of PVC-DTZ-Cu (Ⅱ): PVC: o-NPOE: potassium tetraphenylborate (KTPB) In the buffer system, the linear response is in the range of 10 ~ (-2) ~ 2 × 10 ~ (-6) mol / LSCN ~ - with a slope of 54:1 mV / dec and a detection limit of 8 × 10 -7 mol / L. The mechanism of the interaction between anion and carrier was studied, which showed that SCN ~ - interacted directly with the copper atom in the carrier. Electrode used in wastewater SCN ~ - determination, the results are satisfactory.
