Rapid polarographic determination of chlorine, bromine and iodine in algae

Abstract

A rapid method is described for the polarographic determination of chlorine, bromine and iodine in algae after a single combustion procedure. For the determination of chlorine and iodine, the anodic waves of their ions were recorded. For bromine, on the other hand, the bromide ions were oxidised quantitatively to bromate ions, and the cathodic wave for these was recorded. The method has been tested on several species of algae from the Gulf of Trieste.
