A method is described for the determination of formic acid in air samples. Formic acid was collected on activated charcoal, desorbed with N,Ndimethylformamide and converted into p-bromophenacyl formate. The derivative was analyzed by high-performance liquid chromatography with UV detection (254 nm).
Noble metal chlorides 'RhC13"3H20', PdC12 and 'IrC13 "xH20' ) have been evaluated as catalyst precursors for the decomposition (HCO2H ~ H 2 + CO2), dehydration (HCO2H ~H20 + CO) and air oxidation (2HCO2H + O z ~2H20 + 2CO2) of 88% HCO2H at 75-80 ~ RhC13 under these conditions is an active oxidation
