Hydrometallurgical stepwise separation of alumina and recovery of aluminum fluoride from waste anode cover material of aluminum electrolysis

Abstract Anode cover material holds marked importance owing to its effect of maintaining the thermal balance of aluminum reduction cells, and is categorized as solid waste because of its continuous accumulation. However, cover materials contain large amounts of alumina and fluoride; thus, can be considered for strategic resource recovery. This research has developed a process […]

Op-ed: Are we getting dumber?

Endocrine-disrupting chemicals are an assault on children’s developing brains. Brain function, especially in children, is often evaluated by intelligence tests resulting in an Intelligence Quotient or “IQ.” IQ scores, after having increased for most of the 20th century, have been going down since the mid-1990s. The decline is well documented across Europe, the U.S. and […]

Management of Solid Waste Containing Fluoride—A Review

Abstract Technological and economic development have influenced the amount of post-production waste. Post-industrial waste, generated in the most considerable amount, includes, among others, waste related to the mining, metallurgical, and energy industries. Various non-hazardous or hazardous wastes can be used to produce new construction materials after the “solidification/stabilization” processes. They can be used as admixtures […]

Students give Wikipedia dental content a checkup

May 25, 2022 — University of Toronto dental students are monitoring dental and oral health content on Wikipedia to ensure it is accurate and properly cited. The university’s chapter of the Wikipedia Collaboration of Dental Schools (WCODS) has been updating information for the last three years. Though some don’t view Wikipedia as a credible source, […]

Fast, efficient fluorine-based desalination membrane to purify saltwater

Clean water scarcity is a major issue in today’s world, and the problem is only going to worsen with a changing climate. Desalinating brackish water or seawater is an established method to produce drinkable water, but it comes with huge energy costs. There’s no shortage of creative devices in the works, either using heat to […]

Kairos launches advanced nuclear development consortium

Photo: Bruce nuclear power plant US-based Kairos Power said on 20 April it had assembled leading North American utilities and generating companies to launch an advanced nuclear development consortium named Kairos Power Operations, Manufacturing and Development Alliance (Kairos Power-OMADA) to advance the development of the company’s advanced fluoride salt-cooled high-temperature reactor (KP-FHR) technology. Current member […]

Transformation and migration mechanism of fluorine-containing pollutants in the pyrolysis process of spent lithium-ion battery.

Highlights Adsorption of electrodes to electrolyte can lead to fluorine-containing residues. Melting PVDF prevents the deep removal of fluorine-containing pollutants. A synergistic transformation mechanism of fluorine during pyrolysis is proposed. Abstract Pyrolysis is an effective method to remove organics (e.g. electrolytes and binders) from spent lithium-ion battery (LIB). In this study, the co-pyrolysis characteristics of […]

WHO: Prevention and treatment of dental caries with mercury-free products and minimal intervention

Note from Fluoride Action Network: The World Health Organization (WHO) released the first of a new series of “briefing notes” on oral health advocating fluoride toothpaste, and other topical interventions, to reduce dental caries. There is no mention of fluoridation. On page 1v: Funding source: funds received from the WHO voluntary contributions from The Borrow […]

Sustainable groundwater treatment technologies for underserved rural communities in emerging economies

Highlights Proven contaminant-specific treatment technologies can treat groundwater sustainably. Technologies are applicable to underserved rural communities. Treatment technologies can be traditional, advanced, or experimental. Enabling environmental and societal factors impact technology acceptance. Water quality parameters may impact or interfere with the technology performance. Abstract Worldwide, about one out of two people depend on groundwater resources […]
