Detection of Chemical Warfare Agents with a Coated Piezoelectric Quartz Crystal

摘要

Copper complexes have been evaluated for the detection of organophosphorous compounds in air. Diisopropyl methylphosphonate (DIMP) was used as a model for the phosphorous esters. Bidentate copper complexes possessed the highest activity for DIMP; and this effectiveness was evaluated by chemically binding the complex to XAD-4, an experimental resin polymer. The calibration curve is linear between 0 and 20 ppb DIMP (the range investigated). No significant interference from automobile exhaust gas, chosen as a possible pollutant, was observed. (Author)
