本文研究了使用酸度、成膜时间以及BLM形成液的使用寿命对铂基质十六烷基三辛基碘化扶修饰BLM碘离子传感器性能的影响．结果表明，在20±2℃环境温度下，该传感器膜的形成时间为4～5min；在pH为5．0～10．0酸度范围内对碘离子具有好的响应．以0．1mol／LNaCl为底液，其线性范围为10－6～10－2mol／L[I-]，响应斜率为57mV／pC，符合能斯特响应．BLM形成液在三个月内使用无明显变化．
In this paper, the effects of acidity, film formation time and service life of BLM solution on the performance of platinum-based hexadecyl trioctyl iodide modified BLM iodide ion sensor were studied. The results show that the sensor membrane formation time is 4 ~ 5min at 20 ± 2 ℃ ambient temperature and good response to iodide ion in the pH range of 5.0 ~ 10.0. The linear range of 10-6-10-2 mol / L [I-] and the response slope of 57mV / pC were 0.1 mol / L NaCl as the bottom liquid, which corresponded to Nernst response. There was no significant change in the use of BLM-forming fluid within three months.
