以合成的二种含16-冠-5衍生物的肉桂酸酯分别制得光聚合敏感膜涂铜棒和PVC膜铊(1)离子电极。涂铜棒电极对Tl~+的响应线性范围为3×10~(-5)～1×10~(-2)mol/L,斜率为48mV/pTl~+,选择系数K_(Tl)_+~(pot),k~+=0.12比之相应的PVC膜电极有较长的寿命。
The photopolymerization sensitive membrane coated copper rods and PVC membrane thallium (1) ion electrode were prepared with two cinnamate derivatives containing 16-crown-5 derivatives, respectively. The linear response range of copper electrode coated Tl ~ + is 3 × 10 -5 mol · L -1 × 10 -2 mol / L and the slope is 48mV / pTl ~ +. The selection coefficient K_ (Tl) _ + ~ (pot), k ~ + = 0.12 than the corresponding PVC membrane electrode has a longer life expectancy.
