Abstract

Determin. of halide ions, esp. Cl-, Br- and I-, and without interference, by means of electrodes sensitive to these ions, in the presence of H2S or sulphides comprises destroying the H2S and/or the sulphides by oxidn. during prepn. of the sample prior to the determn. The pH >8 using oxidn. products having a standard potential >=+ 300 mV, and which cannot be detected by the halide sensitive electrode. With continuously functioning analysis appts. a buffer enriched with oxidn. prodn. and the sample are moved by a double channel feed pump, and subsequently mixed.
