Abstract

There is provided an apparatus for continuous measurement of ion concentration in solutions by means of ion sensitive electrodes, which apparatus consists of an electrode containing measuring cell and a dosaging device. This apparatus is particularly suited for measuring cyanide ion concentration in strong hydrochloride solution in the presence of cyanogen chloride. The dosaging device contains a degassing section and a reflecting plate to which the supply means for the working solution to be measured and for the necessary auxiliary reagents are directed, the supply means being in the form of screens or nozzles.
