摘要：

Dissolved oxygen concentrations in dimethylformamide were determined by a modified Winkler method with small sample sizes and no special control of ambient temperature and pressure. The concentrations measured covered a range 0.008-2.59 mM with a relative deviation of less than 1%. Both the oxygen concentrations determined by this method and polarographic diffusion currents were linear functions of the mole fraction of oxygen; therefore a polarographic reduction of oxygen can be used for rapid determination of oxygen in this solvent. © 1969.
