METHOD FOR DETECTING A CONCENTRATION OF CHLORATE-IONS IN AN AQUEOUS SOLUTION, APPARATUS FOR DETECTING A CONCENTRATION OF CHLORATE-IONS AND CONTROL UNIT

摘要

The invention relates to an apparatus, a control unit and amethod for detecting a concentration of chlorate-ions in anaqueous solution (W) containing different types of chlorineoxidants. By-aqueous solution (W) to trigger a transformation ofsubstantially all chlorine oxidants and/or chlorine thereinto chloride and/or chlorate,-contained in the defined volume (V), a solution can beprovided that enables a simple and cheap measurement for aconcentration of chlorate ions in an aqueous solution andthat is capable for online measurement of such chlorateconcentrations.
