Organic halogen group parameters in ground water investigations

摘要: Abstract A set of analytical methods for the determination organic halogen group parameters AOX, EOX and VOX has been developed tested applicability in ground water studies. The can be applied range 1–100 μg ct/L with a relative standard deviation 5–10%. are unbiased by interference from many common constituents waters, but high concentrations iodide sulphide may bias AOX determination. Highly humic waters heavily polluted volatile, non-halogenated organics might exhibit reduced recoveries VOX, respectively. Each method contributes information on nature halogens respect to volatility polarity, as demontrated recovery study selected test compounds.
