“…All the studies highlight the importance of oxygen-based functional groups and activated carbon π-electrons. Consequently, the radionuclides could either form complexes/cation exchange with the oxygenbased groups (Khandaker et al 2021), interact with aromatic π-electrons of the activated carbon basal planes (Cho et al 2020), or physically bind onto the activated carbon pores (Khandaker et al 2018). During the adsorption of uranium ions, Nezhad et al (2021) and Rout et al (2016) noted that improved adsorption is achieved at decreasing solution acidity since the electron lone pair from the negatively charged oxygen-based groups form complexes with empty uranium ions orbitals.…”

Access to drinkable water is becoming more and more challenging due to worldwide pollution and the cost of water treatments. Water and wastewater treatment by adsorption on solid materials is usually cheap and effective in removing contaminants, yet classical adsorbents are not sustainable because they are derived from fossil fuels, and they can induce secondary pollution. Therefore, biological sorbents made of modern biomass are increasingly studied as promising alternatives. Indeed, such biosorbents utilize biological waste that would otherwise pollute water systems, and they promote the circular economy. Here we review biosorbents, magnetic sorbents, and other cost-effective sorbents with emphasis on preparation methods, adsorbents types, adsorption mechanisms, and regeneration of spent adsorbents. Biosorbents are prepared from a wide range of materials, including wood, bacteria, algae, herbaceous materials, agricultural waste, and animal waste. Commonly removed contaminants comprise dyes, heavy metals, radionuclides, pharmaceuticals, and personal care products. Preparation methods include coprecipitation, thermal decomposition, microwave irradiation, chemical reduction, micro-emulsion, and arc discharge. Adsorbents can be classified into activated carbon, biochar, lignocellulosic waste, clays, zeolites, peat, and humic soils. We detail adsorption isotherms and kinetics. Regeneration methods comprise thermal and chemical regeneration and supercritical fluid desorption. We also discuss exhausted adsorbent management and disposal. We found that agro-waste biosorbents can remove up to 68–100% of dyes, while wooden, herbaceous, bacterial, and marine-based biosorbents can remove up to 55–99% of heavy metals. Animal waste-based biosorbents can remove 1–99% of heavy metals. The average removal efficiency of modified biosorbents is around 90–95%, but some treatments, such as cross-linked beads, may negatively affect their efficiency.

“…In this way, PB or PBA were linked to a matrix formed by silica or glass [29]. The adsorbents were also incorporated into a crosslinked, bead-type copolymer resin composed of polystyrene (PS) and divinylbenzene (DVB) [30]. PB has also been immobilized by means of a linkage of polydopamine (PD) on the surface of nanofibers fabricated by electrospinning of polyacrylonitrile (PAN) [31], on poly(vinyl alcohol) (PVA) sponge [32,33], caged in a gel of sodium alginate [34], in the same colloid to develop an intestinal release delivery system [35], in spongiform adsorbents [36], bonded to sepiolite (hydrated magnesium silicate) [37], embedded into a binder matrix [38], in porous cellulose aerogel [39] or in microporous carboxymethyl cellulose nanofibrils membranes [40].…”

Prussian blue (PB) and PB analogues (PBA) are coordination network materials that present important similarities with zeolites concretely with their ability of adsorbing cations. Depending on the conditions of preparation, which is cheap and easy, PB can be classified into soluble PB and insoluble PB. The zeolitic-like properties are mainly inherent to insoluble form. This form presents some defects in its cubic lattice resulting in an open structure. The vacancies make PB capable of taking up and trapping ions or molecules into the lattice. Important adsorption characteristics of PB are a high specific area (370 m2 g−1 determined according the BET theory), uniform pore diameter, and large pore width. PB has numerous applications in many scientific and technological fields. PB are assembled into nanoparticles that, due to their biosafety and biocompatibility, can be used for biomedical applications. PB and PBA have been shown to be excellent sorbents of radioactive cesium and radioactive and nonradioactive thallium. Other cations adsorbed by PB are K+, Na+, NH4+, and some divalent cations. PB can also capture gaseous molecules, hydrocarbons, and even luminescent molecules such as 2-aminoanthracene. As the main adsorptive application of PB is the selective removal of cations from the environment, it is important to easily separate the sorbent of the purified solution. To facilitate this, PB is encapsulated into a polymer or coats a support, sometimes magnetic particles. Finally, is remarkable to point out that PB can be recycled and the adsorbed material can be recovered.

“…Among various techniques, the ionexchange process offers the unique advantages of the ease and low-cost of operation. Various natural and synthesized materials are capable of adsorbing Cs + via the ion-exchange process, such as clay, [15][16][17][18] mica, 19,20 zeolite, 21 titanate, 22 hydroxides 23 and Prussian blue; 24,25 however, the slow Cs + adsorption rate and low ion-exchange capacity lead to unsatisfactory Cs + removal efficiency.…”
