Description
Background: The article presents the results of studies performed in order to develop a new method of airborne potassium bromate(V) determination at workplaces.
Methods: The method is based on a collection of the inhalable fraction of potassium bromate(V) using
the IOM Sampler, then extraction of bromates with deionized water and chromatographic analysis of the obtained solution. The analysis was performed using ion chromatography with conductometric detection. The tests were performed on a Dionex IonPacAS22 analytic column (250 4 mm, 6 mm) with AG22 precolumn (50 4 mm 11 mm).
Results: The method provides for potassium bromate(V) determination within the concentration range of 0.043 O 0.88 mg/m3 for an air sample of 0.72 m3 in volume, i.e., 0.1e2 times the exposure limit value as proposed in Poland. The method was validated in accordance with PN-EN 482. The obtained validation data are as follows: measuring range: 3.1e63.4 mg/mL, limit of detection (LOD) 1⁄4 0.018 mg/mL and limit of quantification (LOQ) 1⁄4 0.053 mg/mL. The developed method has been tested in the work environment, on laboratory employees having contact with potassium bromate(V).
Conclusion: The analytical method allowed the determination of the inhalable fraction of airborne potassium bromate(V) at workplaces and can be used to assess occupational exposure.
