Selenium and its compounds. Method of determining selenium and its compounds in workplace air
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2014, Vol 30, Issue 1
Abstract
This method is used for determining selenium and its compounds in workplace air. It is based on stopping selenium on a membrane filter, mineralizing the sample with concentrated nitric acid and preparing the solution for analysis in diluted nitric acid. Selenium in the solution is determined with atomic absorption spectrophotometry with an air-acetylene flame. The determination limit of the method is 0.01 mg/m[sup]3 [/sup](for a 720-L air sample). The developed method of determining selenium and its compounds has been recorded as an analytical procedure (see Appendix).
