Estimation of unsaturated hydrocarbon pollutants in air based on selective gas chromatography with ozone.

摘要: Regular monitoring of toxic organic pollutants in air is a very important issue environmental pollution control. Among these, unsaturated hydrocarbon (UHP) such as ethylene and β-propylene another ¶18 olefins are prime importance. A fast method for the individual identification UHPs proposed. This based on gas-chromatographic separation with selective detection compounds (UOC) chemical reaction UOC ozone gas phase. In view mathematical model derived this ozonation process, comparison FID-chromatogram ozonogram can be carried out contaminants. performed without preliminary presence main components. The provides high sensitivity (< 0.005 to 0.72 mass %) selectivity.
