Highly efficient enrichment and adsorption of rare earth ions (yttrium(III)) by recyclable magnetic nitrogen functionalized mesoporous expanded perlite

WITHDRAWN: Lichens as Biomonitors of Air Pollutants Deposition: Strategically Important Element Pollution 

“…It has the effect of refining the grains of magnesium alloys, can reduce the amount of calcium required in magnesium-based alloys and may improve the properties of the alloy as well (Cheng et al, 2021). The high content of rare earth element yttrium in various products results in the accumulation in the body through the food chain, and endanger the health by inhibiting the growth of pre-osteoblasts and poisoning the nervous system (Gonzalez et al, 2015;Liu et al, 2021). Cerium (Ce) is the most abundant rare earth metal found in the earth's crust (Kurian, 2020).…”

Selective Dissolution and Separation of Rare Earths Using Guanidine-Based Deep Eutectic Solvents

“…As an intermediate product in the producing of rare earth functional materials, REOs have always been the important bulk commodity in the world trade struggle . The ceramic and photography industries including autophagy and photovoltaic and laser materials are major consumers of REOs. − However, rare earth elements are always associated with each other in minerals, such as bastnasite, monazite, loparite, ion adsorption deposits, and so on. , Due to their similar physical and chemical properties, preparation of high purity REOs is difficult and indirect. , …”

“…4−6 However, rare earth elements are always associated with each other in minerals, such as bastnasite, monazite, loparite, ion adsorption deposits, and so on. 7,8 Due to their similar physical and chemical properties, preparation of high purity REOs is difficult and indirect. 9,10 Production of each ton of high purity REOs will produce nearly 2000 t of slag, 1000 t of wastewater full of heavy metals, 9600−12000 m 3 of sulfide and hydrofluoric acid, and 2 m 3 of radioactive solid waste.…”

In situ synthesis of a GO/COFs composite with enhanced adsorption performance for organic pollutants in water

“…This could be due to n–π EDA interactions between electron depleted sites on carbon-based materials and organic matter containing lone electron pairs of oxygen or nitrogen. 57,58 The –OH group on 1-naphthol was dissociated to form –O − at high pH. The results showed that the electron donor electron intensity increases, resulting in n–π EDA interactions.…”
