Growing Atmospheric Emissions of Sulfuryl Fluoride
See FAN’s background on Sulfuryl fluoride Abstract The potent greenhouse gas sulfuryl fluoride (SO2F2) is increasingly used as a fumigant, replacing methyl bromide, whose structural and soil fumigation uses have been phased out under the Montreal Protocol. We use measurements on archived air samples and in situ observations from the Advanced Global Atmospheric Gases Experiment […]

Voriconazole-induced periostitis
Abstract Voriconazole is a fluorinated drug from the triazole group that is widely used in the prophylaxis and treatment of fungal infections in immunosuppressed patients. Chronic use of this medication can generate, as an adverse effect, a multifocal, asymmetric, diffuse and nodular periosteal reaction, associated with severe and disabling skeletal pain and elevated alkaline phosphatase […]

Oil company begins major new use of ionic liquids
In a milestone for the industrialization of ionic liquids, Chevron has started up an alkylation unit at its Salt Lake City refinery that uses an ionic liquid catalyst instead of the traditional hydrofluoric or sulfuric acid. Alkylation reacts isobutane with olefins such as butene and propylene to create octane and other fuels. The Salt Lake […]

Why providing alternatives to SF6 and other greenhouse gases is important for carbon reduction initiatives
More companies have committed to renewable energy, energy efficiency, and electric vehicle adoption. The urgency to act on climate change has never been greater, and, in the absence of global regulation, companies are voluntarily stepping up to fill the gap. As of the publication of this blog post, more than 1000 companies have set public […]

New Exotic Isotope of Fluorine Discovered: Fluorine-13
Fluorine is the chemical element with the symbol F and atomic number 9. It is the most chemically reactive element on the periodic table and the lightest member of the halogen elements. At standard conditions fluorine exists as a highly toxic, pale yellow diatomic gas. It has 18 known isotopes ranging from 13F to 31F […]

Novel aluminium (hydr) oxide-functionalized activated carbon derived from Raffia palm (Raphia hookeri) shells: Augmentation of its adsorptive properties for efficient fluoride uptake in aqueous media
Highlights RPSAC and ACRPSAC synthesized from Raffia palm shell biomass. ACPSAC had enhanced porosity and BET-surface area of 715.80 mg/g. Adsorptive removal performance of adsorbents for fluoride compared. Excellent fluoride adsorption capacity of 4.10 mg/g for ACRPSAC. Fluoride adsorption describes well with Langmuir model. Regeneration of ACRPSAC possible by recoating with Aluminium (hydr) oxide. Abstract […]

NRK and Expressen Report Fluoro Testing Device Flawed
But what happens in the wax bus matters too: Sweden’s biathlon wax bus flexes. (Photo: NordicFocus) Over the past few years, FasterSkier has reported on per-fluorinated waxes, powders, liquids, and pastes. Entities like the Environmental Protection Agency (EPA) and Europe’s equivalent, the European Environment Agency, are phasing out eight-chain fluorocarbons. We know, after diving into […]

Fluoride removal by thermally treated egg shells with high adsorption capacity, low cost, and easy acquisition
In this study, the use of eggshells was suggested as an adsorbent for fluoride removal, and their mechanism of fluoride removal was investigated. The eggshells underwent thermal treatment to improve their adsorption capacity; 800 °C was found to be the optimal temperature for treatment. Eggshells thermally treated at 800 °C (ES-800) were mainly composed of […]
