摘要：

A simple and reliable double-cell device with three ion-selective membranes for fluoride determinations in a continuous-flow system with an increased slope factor is presented. The relative standard deviation for the analysis of environmental waters was 0.01-0.03 and the slope factor was 113-44 mV pF-1, depending on the fluoride concentration level; the sampling rate was 120 h-1.
