摘要
该文用硒、碲对锑 pH 电极进行改性,制备了锑/硒化锑 pH 电极和锑/碲化锑 pH 电极。锑/硒化锑pH 电极在 pH=2～9范围内呈线性响应,响应斜率为55 mV/pH;锑/碲化锑 pH 电极在 pH=3～7范围内呈线性响应,响应斜率为53 mV/pH。改性后的锑电极改善了原有锑 pH 电极的电位漂移特性。
Sb/Sb2Se3 and Sb/Sb2Te3 pH electrodes were prepared and their response characteristic of the electrode were studied in this paper. Sb/Sb2Se3 pH electrodes showed a linear response in the range of 2-9 pH with a response slope of 55 mV/pH. Sb/Sb2Te3 pH electrodes showed a linear response in the range of 3 -7 pH with a response slope of 53 mV/pH. The potential stability of Sb/Sb2Se3 and Sb/Sb2Te3 pH electrodes have been further improved as compared to Sb/Sb2O3 pH electrodes.
