Pentachlorobenzene (PeCB) is a chemical compound with the molecular formula C₆HCl₅ which is a chlorinated aromatic hydrocarbon. It consists of a benzene ring substituted with five chlorine atoms. PeCB was once used industrially for a variety of uses, but because of environmental concerns there are currently no large scale uses of PeCB. Pentachlorobenzene is a known persistent organic pollutants (POP), classified among the "dirty dozen" and banned globally by the Stockholm Convention on Persistent Organic Pollutants as of 2011.
Method for determining pentachlorothiophenol in rubber
The present application relates to the determination of pentachlorothiophenol in rubber, comprising the following steps: (1) pyrolysis gas chromatography mass spectrometry test standard solution; (2) draw standard curve; (3) sample test; (4) sample qualitative judgment; (5) sample quantitative calculation result. The present application optimizes the quantitative method of pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) for detecting the content of pentachlorothiophenol in rubber products, and quickly confirms the content of pentachlorothiophenol in rubber products.
