Abstract

A potentiometric flow injection determination method for bromide ion in a developer was proposed, by utilizing a flow-through type bromide ion- selective electrode detector. The sensing membrane of the electrode was Ag2S-AgBr membrane. The response of the electrode detector as a peak-shape signal was obtained for injected bromide ion in a developer. A linear relationship was found to exist between peak height and the concentration of the bromide ion in a developer in a concentration range from 1.0 x 10-3 to 1.0 x 10-2 mol l-1. The relative standard deviation for 10 injections of a 6 x 10-3 mol l-1 bromide ion in a developer was 1.3% and the sampling rate was ca 17-20 samples h-1. The present method was free from the interference of an organic reducing reagent, an organic substance in a developer sample solution for the determination of bromide ion in a developer.
