An improved ion-selective electrode for perchlorate.
A new liquid-membrane ion-selective electrode for perchlorate ion based on tetrakistri-phenylphosphine silver(I) perchlorate in nitrobenzene is described. Its dynamic range and selectivities relative to most common anions are comparable to those of the Orion model 92-81 perchlorate sensor. However, it suffers much less hydroxide-ion interference than the Orion product.
