Polarographic behaviour of C2-halogen hydrocarbons
Investigations on the polarographic and voltammetric behaviour of organic halogen compounds were carried out in order to obtain information on the redox properties and how to develop determination and detection methods. In this second report the dp-polarographic behaviour of the halogen substituted C2-compounds has been studied in different supporting electrolytes and in various solvents. The electrode processes are discussed and the possibilities for the polarographic determination of the C2-halogen hydrocarbons. The detection limit is 0.25 μg · ml−1 and the linear current-concentration relationship is observed up to 25 μg · ml−1. A simple and rapid method is proposed for the dp-polarographic determination of 1,2-dibromoethane in gasoline; the relative standard deviation for 20 μg · ml−1 is ±1.8%.
