Magnetic hydrophobic cellulose-modified polyurethane filter for efficient oil-water separation in a complex water environment

Removal of uranium from wastewater through Ni–Al-layered double hydroxide@carbon nanotubes functionalized by polyethyleneimine

“…7,8 The removal and recycling of uranium ions from uranium-containing wastewater can lead to not only a decrease in the adverse effects of nuclear wastewater on the natural environment but also reutilization of waste uranium resources. Adsorption has become one of the most commonly used methods [9][10][11][12] for removing uranyl ions from water, and efficient and fast adsorbents must be urgently obtained. [13][14][15] Metal organic frameworks (MOFs), 1,16 magnetic materials, 17,18 silica, 19 polyacrylonitriles, 20,21 hemp fiber, 14,15,22,23 and carbon materials [24][25][26][27] have been used in uranium adsorption.…”

Fast Removal of Tetracycline from Aqueous Solution by Aluminosilicate Zeolite Nanoparticles with High Adsorption Capacity

“…Different types of adsorbents can be designed and used in water treatment technologies, such as nanomaterials, polymers, and green materials. − It is extremely important to develop economical and environmentally friendly wastewater treatment methods and technologies. , However, most of the stated methods are relatively inefficient, produce toxic byproducts, expensive, slow processing, and not used on a large scale. Among the aforementioned methods, adsorption is still one of the most widely used techniques because of its advantages of high efficiency, low cost, and environmental friendliness …”

Nanocrystalline structured ethylene glycol doped maghemite for persistent pollutants removal

“…4,5 Several physical, chemical and biological methods have been applied for wastewater treatment, but the selection of an appropriate material depends by cost operations, less environmental pollution, efficiency, easy separation and reutilization. 1,6,7 Among the techniques available for water treatment the adsorption has been shown to be an efficient and easily optimized process for better performance. [8][9][10] Nanomaterials have attracted considerable interest in research because of their potential to be applied to a several environmental remediation technologies, medicine, petrochemical industries, building materials or catalytic processes.…”

“…has been revolutionary, as they can have applications in various fields such as industries (dye, chemicals, catalysts, aviation), pharmaceutics, medicine, IT, military and also wastewater treatment technologies. 1,6,17,18 In the past few decades, various methods have been reported for synthesizing γ-Fe 2 O 3 nanoparticles (NPs), such as the sol-gel process, 19 modified co-precipitation method, 20 microemulsion, 21 aerosol technology, thermal decomposition, 22 and hydrothermal methods. 23 However, the current preparation methods of γ-Fe 2 O 3 still involve complicated processes and a high cost, thereby needing improvement.…”
