Chloroform Formation by Chlorination of Aqueous Algae Suspensions: Online Monitoring via Membrane Introduction Mass Spectrometry
A técnica MIMS (membrane introduction mass spectrometry) foi utilizada para monitorar a formação de clorofórmio durante a cloração de suspensões aquosas de várias espécies brasileiras de algas verdes e azuis (Microcystis panniformis, Selenastrum sp., Scenedesmus sp., Monoraphidium sp. (strain 354), Monoraphidium sp. (strain 960), and Staurastrum sp.). Foram avaliadas as influências de parâmetro...
متن کاملReversed-phase membrane inlet mass spectrometry applied to the real-time monitoring of low molecular weight alcohols in chloroform.
Reversed-phase membrane inlet mass spectrometry incorporating a hollow-fiber Nafion membrane has been evaluated for the determination of low molecular weight alcohols in chloroform. The hydrophilic Nafion membrane preferentially transports methanol and ethanol, allowing percentage concentrations of the alcohols to be determined in a chloroform matrix. A linear response was observed for ethanol ...
متن کاملAPPLIED CHEMISTRY Photocatalytic Degradation of Phenol and Trichloroethylene: On-Line and Real-Time Monitoring via Membrane Introduction Mass Spectrometry
Membrane introduction mass spectrometry (MIMS) has been applied to monitor and compare in real time the extent by which three photocatalytic remediation processessFenton’s reagent/ UV, ferrioxalate/H2O2/UV, and TiO2/UVsdestroy two common water pollutantssphenol and trichloroethylene (TCE). Continuous MIMS and selected ion monitoring (MIMS-SIM) of both phenol and TCE degradation and CO2 producti...
متن کاملOn-line monitoring of bioreductions via membrane introduction mass spectrometry.
Real-time and on-line continuous monitoring of reactants, intermediates, and final products for dicarbonyl compound bioreduction in a continuous plug flow reactor packed with baker's yeast (Saccharomyces cerevisiae) whole cells immobilized on calcium alginate beads was performed by membrane introduction mass spectrometry (MIMS) via selective ion monitoring.
متن کاملEnvironmental applications of membrane introduction mass spectrometry.
The purpose of this review is to highlight the versatility of membrane introduction mass spectrometry (MIMS) in environmental applications, summarize the measurements of environmental volatile organic compounds (VOCs) accomplished using MIMS, present developments in the detection of semi-volatile organic compounds (SVOCs) and forecast possible future directions of MIMS in environmental applicat...
