Chlorine has been used for decades to disinfect drinking water. An undesirable side effect of this treatment
Question:
Chlorine has been used for decades to disinfect drinking water. An undesirable side effect of this treatment is reaction with organic impurities to create organochlorine compounds, some of which could be toxic. Monitoring total organic halide (designated TOX) is required for many water providers. A standard procedure for TOX is to pass water through activated charcoal, which adsorbs organic compounds. Then the charcoal is combusted to liberate hydrogen halides:
HX is absorbed into aqueous solution and measured by coulometric titration with a silver anode:
When 1.00 L of drinking water was analyzed, a current of 4.23 mA was required for 387 s. A blank prepared by oxidizing charcoal required 6 s at 4.23 mA. Express the TOX of the drinking water as µmol halogen/L. If all halogen is chlorine, express the TOX as µg Cl/L.
