摘　　要：报道了一种以乙基紫为定域体试剂、溶胶—凝胶法制备的碘离子电极,该电极的线性范围为9.0×10-7mol/L—1.0×10-1mol/L,平均斜率为58.4mV/decade,检测下限为7.6×10-7mol/L,适宜pH范围为3.1—11.5.A new ion iodine electrode which uses ethyl violet as electrical active material and the sol-gel technique for prepara- tion is reported, The electrode exhibits the response for ion iodine with a slope of 58.4mV/decade over the concentration range of 9.0 ×10^-7-1.0×10^-7 mol/L, at pH 3.1--11.5. The detection limit is 7.6 ×10^-7 mol/L.
