Abstract:Kaolinite functionalized
by the μ-oxo Fe3+-phenanthroline
complex (Fe+3Phen) was selected to test its ability to
efficiently remove and store gaseous heptanethiol (HPT). Spectroscopic
techniques, elemental analysis, and thermal analysis coupled with
evolved gas mass spectrometry were employed to characterize the material
before and after the exposure to the gas and to define the adsorption
process. The amount of HPT trapped by the functionalized kaolinite
after 60 days is 0.10940 moles per 100 g of kaolinite w… Show more
“…Kaolinite hybrid material, functionalized by the μ-oxo Fe 3+ -phenanthroline complex, was selected to test its ability to efficiently remove and store gaseous heptanethiol. Evolved gas analysis by mass spectrometry was employed to characterize the material before and after the exposure to the gas and to define the adsorption process [ 161 ].…”
Advances in on-line thermally induced evolved gas analysis (OLTI-EGA) have been systematically reported by our group to update their applications in several different fields and to provide useful starting references. The importance of an accurate interpretation of the thermally-induced reaction mechanism which involves the formation of gaseous species is necessary to obtain the characterization of the evolved products. In this review, applications of Evolved Gas Analysis (EGA) performed by on-line coupling heating devices to mass spectrometry (EGA-MS), are reported. Reported references clearly demonstrate that the characterization of the nature of volatile products released by a substance subjected to a controlled temperature program allows us to prove a supposed reaction or composition, either under isothermal or under heating conditions. Selected 2019, 2020, and 2021 references are collected and briefly described in this review.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
