Abstract |
o-Phenylenediamine (OPD) vapour is drawn through a bubbler containing acetic anhydride to form the relatively stable 1,2-diacetamidobenzene. The acetic anhydride solution is analysed by high-performance liquid chromatography, and the diacetamido derivative quantified. The analysis is linear for standard solutions in the range of 0.5µg to 0.5mg/ml. Air concentrations of OPD were prepared by passing a metered stream of nitrogen through a glass tube packed with OPD crystals and diluting the stream with metered air to achieve the desired level. Collection efficiency and conversion to the derivative were close to 100% at vapour concentrations of 0.09mg/m3, and approx. 60% at 0.02mg/m3. o-Toluenediamine interfered with the analysis. |
