title: [Photometric method of the detection of magnesium oxide in the working zone air after using magnesium caustic dust].
abstract: The contributors proposed a new highly sensitive selective technique of magnesium oxide detection, based on the Congo red and salicylic acid reaction. The minimal detection level is 0.25 mg of magnesium oxide in the analyzed sample volume. The range of measured concentrations varies from 0.01 to 0.4 mcg/ml. The express technique is simple and selective with Ca (II), Fe (III), AI (III).
