Recycling of waste toner derived from exhausted printer cartridges as adsorbent for defluoridation of water.
Highlights Exhausted printer cartridge’s toner (PCt) powder as adsorbent for fluoride removal. It is a waste-to-wealth concept of reusing of remaining toner powder. This carbon ferric composite (toner) has 60 mg/g adsorption capacity. It shows the physical adsorption process between PCt and fluoride ions. Abstract Due to the broad adoption of electronic and electrical equipment and […]International Water Treatment
Benchmark: Li-ion battery boom driving fluorspar demand.
Fluorspar demand from the lithium-ion battery sector is expected to exceed 1.6 million tonnes by 2030, representing a significant portion of the overall market, according to Benchmark’s new Fluorspar Market Outlook. This mineral, primarily composed of calcium fluoride (CaF2), holds potential beyond its traditional uses in refrigerants, steelmaking and aluminum production. Fluorspar is mainly produced […]International Batteries
Unusual bridging fluorine discovered in one-of-a-kind interhalogen ion – [Br4F21] –
For the first time, chemists have synthesised an interhalogen compound exhibiting a unique central fluorine atom coordinated by four BrF5 groups.1 The one-of-a-kind interhalogen ion in [NMe4][Br4F21]·BrF5 represents the first example of a central tetracoordinated fluorine bridging to neither metal nor hydrogen atoms. Tetracoordinated fluorine atoms are known in ionic compounds, for example in CaF2. […]International Chemical Industry

Breakthrough research could destroy ‘forever chemicals’
Chemists have made a major advancement in efforts to break down certain so-called forever chemicals, according to headline-grabbing new research that still comes saddled with notable caveats, including scalability. Northwestern University researchers announced yesterday that they had pinpointed a method to break apart a group of PFAS compounds without using either extreme temperatures or energy […]International Perfluorinated chemicals

Fluorinated Materials as Positive Electrodes for Li- and Na-Ion Batteries
Abstract Fluorine is known to be a key element for various components of batteries since current electrolytes rely on Li-ion salts having fluorinated ions and electrode binders are mainly based on fluorinated polymers. Metal fluorides or mixed anion metal fluorides (mainly oxyfluorides) have also gained a substantial interest as active materials for the electrode redox […]International Batteries

PFOA in rain worldwide exceeds EPA advisory level
Amounts of PFAS in precipitation called “practically irreversible” Credit: Shutterstock Even in remote areas, precipitation contains levels of PFOA higher than the EPA recommends for drinking water, reserachers say. Rain and snow around the world contain higher concentrations of a toxic, persistent industrial chemical than the US Environmental Protection Agency’s advisory level for the substance […]United States, ACSH International Perfluorinated chemicals
