Experimental and model study for fluoride removal by thermally activated sepiolite.
Note from Fluoride Action Network: “Since all methods [to remove fluoride] produce a sludge with very high concentration of fluoride that has to be disposed of, only water for drinking and cooking purposes should be treated, particularly in the developing countries.” Reference: Fluorosis (see Interventions), World Health Organization Highlights Thermal treatment for sepiolite improved the […]

3M to increase fluoroelastomer capacity
3M Paris – 3M is set to bring significant new fluoroelastomer capacity on stream in response to increasing global-market demand, according to Laurent Sportouch, the company’s key account manager Elastomers France. “3M is building more FKM polymerisation capacity to align with growing global demand,” he said in a presentation at a recent French rubber industry […]

Shape of volcanic ash influences contamination of water sources in volcanically active regions
Kilauea, a famous Hawaiian volcano [see photo], erupts lava and basaltic ash that has high concentrations of fluorine. Credit: M. Patrick, USGS Contaminants from volcanic eruptions leach into water at different rates depending on the shape of the volcanic ash particles, according to new research that could enhancing scientists’ ability to predict water quality risk […]

Effective neutralization of chemical warfare agents (HD, VX) by Me-DABCOF: a small molecule with dual action.
Abstract The ability of mono N-methyl-1,4-diazabicyclo[2.2.2]octane fluoride (Me-DABCOF, 1) to act as a bifunctional reagent that effectively and universally neutralizes both the persistent and extremely toxic blister agent HD and the nerve agent VX in nearly neutral aqueous solution, alumina powder or a hydrogel formulation, is described. *Original abstract online at https://pubs.rsc.org/en/content/articlelanding/2019/CC/C9CC07011G#!divAbstract Print PDF

Preparation and characterization of novel green synthesized iron–aluminum nanocomposite and studying its efficiency in fluoride removal
Highlights Green synthesized iron-aluminium nanocomposite, adsorption capacity ?42.95?mg/g and fluoride removal 82.1%. Langmuir model best fitted the equilibrium data with monolayer adsorption capacity of 28.07?mg/g at 313?K. The reaction followed pseudo second order kinetics and multistage diffusion control process. Fluoride contaminated water from subparts of India resulted in 82.6 and 83% removal efficiency. Abstract A […]

What’s The Deal With Fluoro Wax?
About a year ago, racers and parents across the country noticed something peculiar about the shelves at their local ski shops. The coveted and pricey bars of fluorocarbon wax that racers had used for that extra bit of speed on race day for decades had become near-impossible to find from coast to coast, as well […]

Sulphur hexafluoride (SF6 ).Climate change: Electrical industry’s ‘dirty secret’ boosts warming
Note from Fluoride Action Network This article has excellent graphics which we couldn’t capture. Recommend that you read this article online at BBC here It’s the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the BBC has learned. Sulphur hexafluoride, or SF6, is widely used in the electrical […]

Analysis of equilibrium, kinetic, and thermodynamic parameters for biosorption of fluoride from water onto coconut (Cocos nucifera Linn.) root developed adsorbent
Abstract Drinking water with higher fluoride levels results in serious irremediable health problems that have attained a startle all over the world. Researches focused towards deflouridation through the application of biosorbents prepared from various plants are finding greater scope and significance. Present research is done on Cocos nucifera Linn. (coconut tree) one of the very […]
