Determination of Halogen Elements in Volatile Organohalogen Compounds by the Wickbold Combustion Pretreatment Method and Ion Chromatography

Abstract

A quantitative analysis method of halogen elements in volatile organohalogen compounds was established by the Wickbold combustion pretreatment in an enclosed system and ion chromatography. The sample pretreatment parameters of Wickbold combustion were experimentally optimized, and using the determined optimal pretreatment parameters, the reproducibility was estimated by ion chromatography. As a comparison for real samples, NIST certified reference materials (CRMs) were analyzed for the recovery efficiency and reproducibility.

Determination of chlorine in Hf precursors by high-resolution inductively coupled plasma mass spectrometry

“…The analysis time per sample was 20 minutes, and the limit of detection (LOD) was 0.14 mg kg −1 , showing a limit in detecting μg kg −1 levels. 9 The disadvantages of measuring chlorine ions using IC are that it has a high detection limit and can only measure anionic substances, such as Cl − , making it difficult to measure all remaining chlorine.…”
