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 […]

Removal of fluoride in membrane-based water and wastewater treatment technologies: Performance review
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 Fluoride affects the environment and conventional […]

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 […]

Adsorption of fluoride from aqueous solution by fly ash cenospheres modified with paper mill lime mud: Experimental and modeling
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 A low-cost fly ash cenospheres modified […]

Fluoride removal by palm shell waste based powdered activated carbon vs. functionalized carbon with magnesium silicate: Implications for their application in water treatment.
Abstract In this study, palm shell activated carbon powder (PSAC) and magnesium silicate (MgSiO3) modified PSAC (MPSAC) were thoroughly investigated for fluoride (F–) adsorption. F– adsorption isotherms showed that PSAC and MPSAC over-performed some other reported F– adsorbents with adsorption capacities of 116 mg g-1 and 150 mg g-1, respectively. Interestingly, the MgSiO3 impregnated layer […]

Evaluation the Feasibility of Short-Term Electrodialysis for Separating Naturally Occurring Fluoride from Instant Brick Tea Infusion
Abstract BACKGROUND: Removing excessive naturally occurring fluoride from tea and/or infusions is difficult because the process has low efficiency and causes secondary pollution. In this study, a novel electrodialysis (ED) technology was developed. We examined the effect of crucial parameters (electrolyte concentration, operation voltage, ED duration, and initial concentration of the tea infusion) on the […]
