Highly efficient extraction of rare earth elements and others ions from green phosphoric acid medium using TMSEDTA@GO@Fe3O4 core-shell

Adsorption-based Separation and Recovery of Rare Earth Elements

“…However, since the adsorption capacity of these unmodified adsorbents is low (i.e., around 0.01-0.1 mmol/g) (Ehrlich & Lisichkin, 2017), it is impractical to employ these adsorbents for REE separation at an industrial scale. Source for data: Adsorbents 1-2 (Florek et al, 2014), 3-5 (Florek et al, 2015), 6-8 (Perreault et al, 2017), 9-13 (Juère et al, 2016), 14-16 (Hu et al, 2017, 17-20(pH is equilibrium pH) (Zhang et al, 2018), 21 (Artiushenko, Ávila, et al, 2020), 22-25 (Hu et al, 2019, 26-29 (Yantasee et al, 2009), 30 (Zheng et al, 2015), 31 (Amarasekara et al, 2009), 32 (Veliscek-Carolan et al, 2014, 33 (Ogata et al, 2015b), 34-36 (Giret et al, 2018, 37 (Li et al, 2018), 38 (Barrak et al, 2019), 39-40 (Lou et al, 2019), 41 (Kostenko et al, 2019).…”

N-Phenyl acrylamide-incorporated porous silica-bound graphene oxide sheets with excellent removal capacity for Cr(iii) and Cr(vi) from wastewater

“…The functional groups of GO react with the functional groups (-NH 2 , -SH, -COOH, and -OH) of other materials such as silica and the resulting materials can be used for the enhanced adsorption of the target pollutants/metals present in effluents. 40 Silica-based composites are stable and aqua-friendly materials and can be used as efficient adsorbents for the removal of heavy metals. 41 Broad dimensions (large surface area and wide pore size) of the silica-based adsorbents are effective for the improved adsorption of heavy metals.…”
