Fluorine: the T rex of the periodic table
Pass out the nickel superalloy reactor kit, it’s time to tame that most reactive of elements Our lives in the laboratory are seemingly defined by simple borosilicate glass. There are glass flasks, glass columns and glass condensers. It’s gorgeous: a brilliant and transparent material that feels good to the touch and allows you to see […]

Facile method to synthesize efficient adsorbent from alumina by nitric acid activation: Batch scale defluoridation, kinetics, isotherm studies and implementation on industrial wastewater treatment.
Highlights Efficient fluoride removal potential from industrial wastewater. The fluoride removal efficiency was increased from 74.18% to 97.43%. The maximum adsorption capacity of novel adsorbent was 45.75 mg/g at 45°C. Adsorbent exhibited > 99% regeneration efficiency and four cycles of reusability. Abstract The excess amount of fluoride contamination in the groundwater or industrial effluents fosters […]

Top cited publications on fluoride in relation to oral health: a bibliometric analysis
ABSTRACT: The citation count is one of the indications of a manuscript’s impact. The objective of the current study was to identify and analyze the top cited articles published on fluoride in the context of oral health. The articles published from January 1997 to December 2017 on fluoride in the context of oral health were […]

Fluoride contamination, health problems and remediation methods in Asian groundwater: A comprehensive review.
Highlights The status of fluoride contamination in groundwater of Asian countries is reviewed. India, Pakistan and China are critically affected by fluoride contamination. Dental fluorosis is major adverse effect due to fluoride contamination in water. Various defluoridation techniques have been discussed. More research on fluoride decontamination is suggested. Abstract In low concentration, fluoride is considered […]

Waste incineration of PTFE to evaluate potential formation of PFAS in flue gas
Highlights Municipal incineration of PTFE shows no significant generation of studied PFAS. Using pilot scale equipment and paired t-testing minimizes background interference. PTFE produced mainly hydrofluoric acid and carbon dioxide during incineration. Abstract In recent years, concerns over some per- and polyfluorinated alkyl substances (PFAS) have grown steadily. PFAS are a large group of chemical […]

Odisha fisherman nets rare Ghol fish, sells 1 at Rs 6,000/kg
Note from the Fluoride Action Network Wikipedia has to say about the Ghol fish: “Protonibea diacanthus, commonly known as the blackspotted croaker, is a species of fish native to the Indo-Pacific region. This fish is considered amongst the most-expensive variety of the marine fish. Its heart is known as the ‘Sea Gold’, which is said […]

The Dark Side of Fluorine.
Full Text: ABSTRACT: Despite the perceived stability of the C?F bond, chemical instability and drug-metabolizing enzymes can lead to its cleavage. The resulting release of fluoride and formation of certain metabolites may cause safety issues and warrant the medicinal chemists’ attention. Fluorine is an indispensable tool in the medicinal chemists’ toolbox. Due to its small […]

Colgate redesigned the toothpaste tube so it’s actually recyclable… by 2025
The new design will be fully rolled out by 2025. Of the hundreds of thousands of tubes of toothpaste sold in the U.S. each year, most end up in landfills. The tubes, which are usually made of a mix of materials including aluminum, aren’t accepted at typical recycling facilities. Colgate spent the last five years […]
