Diphenylamine. Determining diphenylamine in workplace air with HPLC
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2014, Vol 30, Issue 1
Abstract
A new procedure has been developed for the assay of diphenylamine with high-performance liquid chromatography with a FLD or UV-VIS detector. The method is based on the adsorption of diphenylamine on glass fibre filters treated with sulfuric acid. The trapped diphenylamine is then extracted with methanol and the resulted solutions are analysed with high performance chromatography with ultraviolet or spectrofluorimetric detection. The working range of the analytical method is 0.4 ÷ 16 mg/m[sup]3[/sup] for a 100 L air sam-ple. Limit of quantification: 0.00026 µg/ml (FLD) and 0.02 µg/ml (UV-VIS). The developed method of determining diphenyla-mine has been recorded as an analytical procedure (see Appendix).
