“…However, a wide range of sorbents and biosorbents has been investigated for the last decades for uranium recovery from dilute solutions. Resins offer many possibilities by grafting different functional groups at the surface of macroporous or gel-like polymers (Amphlett et al, 2018a;Amphlett et al, 2018b;Ang et al, 2018;Dlamini et al, 2019;Duval et al, 2019;Kong et al, 2018;Liu et al, 2017;Liu et al, 2018;Negm et al, 2019;Rodas Ceballos et al, 2019;Solgy et al, 2015). This versatility in the functional groups helps in designing materials with higher selectivity for target metals.…”

A high-energy ball milling of magnetite nanoparticles with amino-phosphonic functionalized poly(glycidyl methacrylate) polymer is used for manufacturing a highly efficient magnetic sorbent for U(VI) sorption from aqueous solutions. The Uranyl ions were adsorbed through the binding with amine and phosphonic groups as confirmed by Fourier Transform infrared (FTIR) and X-ray photoelectron spectroscopy (XPS) analyses. The maximum sorption capacity (up to 270 mg U g À1) occurred at pH ¼ 3e4; Langmuir isotherm well describes the sorption process. Small-size particles allow achieving fast uptake (within z90 min of contact); and the kinetic profiles are modeled by the pseudo-second order rate equation. Uranium is successfully desorbed from loaded sorbent using 0.25 M NaHCO 3 solution: Sorbent can be recycled with minimal decrease in sorption and desorption efficiency for at least 6 cycles. The sorbent is efficiently used for U(VI) recovery from the acidic leachates of U-bearing ores (after precipitation pre-treatment). Sorption capacity approaches 190 mg U g À1 despite the presence of high concentrations of Fe and Si: the sorbent has a marked preference for U(VI) (confirmed by distribution ratios and selectivity coefficients).

“…SW and SW-derived products such as chitin and chitosan are used to remove harmful pollutants (Sánchez-Duarte et al 2012 ; Dehghani et al 2018 ; Akhbarizadeh et al 2018 ; Kong et al 2018 ; Yin et al 2019 ). The mechanism involved in removing the pollutants by the SW is adsorption (Fabbricino et al 2013 ).…”

The seafood industry generates waste, including shells, bones, intestines, and wastewater. The discards are nutrient-rich, containing varying concentrations of carotenoids, proteins, chitin, and other minerals. Thus, it is imperative to subject seafood waste, including shrimp waste (SW), to secondary processing and valorization for demineralization and deproteination to retrieve industrially essential compounds. Although several chemical processes are available for SW processing, most of them are inherently ecotoxic. Bioconversion of SW is cost-effective, ecofriendly, and safe. Microbial fermentation and the action of exogenous enzymes are among the significant SW bioconversion processes that transform seafood waste into valuable products. SW is a potential raw material for agrochemicals, microbial culture media, adsorbents, therapeutics, nutraceuticals, and bio-nanomaterials. This review comprehensively elucidates the valorization approaches of SW, addressing the drawbacks of chemically mediated methods for SW treatments. It is a broad overview of the applications associated with nutrient-rich SW, besides highlighting the role of major shrimp-producing countries in exploring SW to achieve safe, ecofriendly, and efficient bio-products.

“…Biosorbents and biopolymers have been frequently used as efficient sorbents for metal recovery [22][23][24][25]; making profit of the presence of reactive groups such as amine (in chitosan, for example, [26]) or carboxylic groups (in alginate, for example, [27,28]). These materials have also been used as encapsulating agents (by hydrogel formation [29][30][31]) and/or as support for functionalization [32][33][34].…”
