The Jacobs-Hochheiser method for the determination of NO<sub>2</sub> was improved by the addition of R-salt (0.2 g l<sup>-1</sup>) and triethanol amine (1 g l<sup>-1</sup>) to the 0.1 N NaOH used as the sampling solution. These compounds were selected from a group of compounds containing reactive H-atoms in the molecules. Sampling efficiency was about 95 per cent and the stoichiometric factor about 90 per cent. © 1971.
