Extracting #lithium from #waste liquids: The method uses #aluminium hydroxide – abundant in Earth’s crust – as a #sorbent for lithium sulphate. It relies on the less stable and more reactive amorphous crystalline polymorph of aluminium hydroxide (Al(OH)3), instead of one of the four highly ordered structures. Researchers at Oak Ridge National Laboratory say it is #cheap, readily #available and easy to handle. See full article here: bit.ly/3RBUpRa

https://lnkd.in/d3-sRfY4 Vivianite is a hydrated iron phosphate mineral (Fe3(PO4)2·8H2O), crystallized in a monoclinic system. It is the endmember of a mineral series known as the vivianite group, where minerals have the general formula A3(XO4)2·8H2O, A is a divalent metal cation and X is phosphorus P or arsenic As. Today, vivianite is attracting interest as a promising material for recovering phosphorous from wastewaters. In fact, the presence in wastewater sludges of soluble iron and phosphorus can lead to vivianite formation. As a crystal, it is a naturally occurring Van der Walls material. It can be easily characterized by means of Raman and infrared spectroscopies. Here we will consider the Raman spectroscopy, precisely that related to the hydroxyl-stretching region. We will propose the deconvolutions in q-Gaussian functions of spectra from RRUFF database, comparing the obtained results with those available from literature. Besides vivianite, we will consider also baricite and bobierrite for comparison (baricite and bobierrite are two other members of the vivianite group). About the hydroxyl-stretching region and the use of q-Gaussians, we take the chance to continue a discussion regarding the Raman spectroscopy of water, discussion that we started in March 2024.

Section VII.C.1.a.vi: Chemical Properties & Applications of Potassium Permanganate The Purple Potentate: Unraveling the Chemical Majesty of Potassium Permanganate in Mineral Processing Abstract In the theatrical world of mineral processing, potassium permanganate (KMnO₄) emerges as a royal figure, clad in its vibrant purple robe, ready to oxidize and transform with regal authority. This analysis delves into the chemical properties and myriad applications of KMnO₄, showcasing its role as both a formidable oxidizing agent and a meticulous cleaner in the realm of mineral beneficiation. From its molecular choreography in oxidation reactions to its environmental ballet in water treatment, we explore how KMnO₄ dances through processes, altering the fates of metals and impurities alike. The study not only highlights its chemical versatility, from breaking down antibiotics to its dramatic reactions in acidic and alkaline symphonies but also scrutinizes the economic and environmental pas de deux it performs on the global stage. Through case studies and theoretical insights, this abstract sets the stage for a deep dive into how potassium permanganate, with its oxidizing prowess, continues to rule the mineral processing kingdom with an iron (or rather, manganese) fist, all while wearing its environmental impact crown. #PotassiumPermanganate, #MineralProcessing, #MiningInnovation, #EnvironmentalTech, #SustainableMining, #OxidizingAgents, #ChemicalEngineering, #GreenChemistry, #WaterTreatment, #OreRecovery, #MiningRegulations, #TechInMining, #EcoFriendlyMining, #CircularEconomy, #MiningIndustry https://lnkd.in/gbBQE-wt

Aerogels manifest hydrophobic characteristics primarily as a consequence of both surface chemical modifications and their distinctive nanoscale structure. The surface chemistry of aerogels, notably silica aerogels, involves the presence of surface groups, such as silanol (-Si-OH). By subjecting these groups to modifications, the introduction of hydrophobic elements, like methyl (-CH3) groups, occurs. This alteration is pivotal in diminishing the aerogel's affinity for water molecules. Simultaneously, the nanoscale structure of aerogels contributes significantly to their hydrophobic nature. The porous framework at this scale establishes an intricate network of interconnected pores. This structuring minimizes the contact area between the aerogel and water, thereby reducing capillary forces and impeding water infiltration. Moreover, the inherent surface energy of aerogels plays a crucial role. Through the incorporation of hydrophobic surface groups and the overall low-density nature of aerogels, a milieu with low surface energy is created. This renders the surface less favorable for water molecules to adhere. In summary, the hydrophobicity of aerogels stems from a nuanced interplay of surface chemical modifications, nanoscale structural intricacies, and the modulation of surface energy, collectively resulting in a material that demonstrates pronounced resistance to water interaction. video: ©Insta- science.feed #stem #aerogel #hydrophobic

Sediment porewater dialysis passive samplers, also known as “peepers,” are sampling devices that allow the measurement of dissolved inorganic ions in the porewater of a saturated sediment. Peepers function by allowing freely-dissolved ions in sediment porewater to diffuse across a micro-porous membrane towards water contained in an isolated compartment that has been inserted into sediment. Once retrieved after a deployment period, the resulting sample obtained can provide concentrations of freely-dissolved inorganic constituents in sediment, which provides measurements that can be used for understanding contaminant fate and risk. To learn more, check out the new #Envirowiki article by Florent Risacher and Dr. Jason Conder at https://bit.ly/40CJQ5w #scientificresearch #peerreviewed
