“…Peaks appeared at 531.5 eV, 532.9 eV and 534.82 eV corresponded to carbon atoms in the forms of –OH/Y–OH, C=O/C–O and COO − , respectively. These groups were derived from the sugars, amino acids and ether, respectively 18 , 44 . The formation of yttrium hydroxide was identified by a negative shifts of –OH from 531.5 to 531.0 eV, and an increase in AC% from 17.09% to 24.8% after biosorption of Y(III) 50 .…”

“…Biosorption belongs to adsorption, and refers to the adsorption process is use biomaterial or biopolymer mainly including fungi, bacteria, yeasts, algae, plant-derived materials as adsorbents 16 . Recently, biosorption has been highly recommended because it has advantages such as low cost, variety, efficient, high selectivity, renewability, and sutiful for treating low concentrations wastewater in comparison with tranditional methods 17 , 18 .…”

“…Biosorption is a quite complex process involving one or more elementary mechanisms such as electrostatic attraction, ion exchange, surface complexation and precipitation 18 , 19 . Ion exchange and surface complexation were considered to be mainly responsible for the adsorption of REEs by Laminaria ochroleuca and Porphyra haitanensis based on inductively coupled plasma mass spectrometry (ICP-MS) and Fourier transformed infrared spectra (FT-IR) analysis 20 .…”

“…It is considered that one and more functional groups (such as hydroxyl, carboxyl, amine and phosphoryl) on the biosorbents surface are vital to the biosorption of REEs as they can influence the surface charge state, the light metal ions in ion exchange, and surface complexation binding sites 16 , 18 . Markai et al 24 analyzed the adsorption functional groups of Bacillus subtilis for Eu(III) at different pH, and they observed that the carboxylic groups were mainly complexed with Eu(III) at pH 5, while phosphoryl and carboxylic were complexed with Eu(III) when pH exceeded 5.…”

The discharge of yttrium containing wastewater is a potential risk to human health. Although biosorption is a promising method to remove yttrium from wastewater, whereas the application of it is limited due to the lack of efficient biosorbents. In this study, the removal of yttrium from wastewater using Serratia marcescens as a biosorbent was conducted. The effects of six parameters including pH (2–5.5), initial yttrium concentration (10–110 mg/L), biosorbent dosage (0.1–0.5 g/L), biosorption time (10–700 min), stirring speed (50–300 rpm) and temperature (20–60 °C) were evaluated. The main parameters were optimized using response surface methodology. The results showed that the adsorption capacity reached 123.65 mg/g at the optimized conditions. The biosorption mechanism was revealed based on a combined analysis using field emission transmission electron microscope-energy dispersion spectrum, Fourier transform infrared spectrophotometer, and X-ray photoelectron spectroscopy. These results revealed that the hydroxyl, carboxyl, and amino groups were the adsorption functional groups for yttrium ions. Biosorption of yttrium by S. marcescens is under the combination of ion exchange, electrostatic attraction and complexation. These findings indicated that S. marcescens can be used as an efficient biosorbent to remove yttrium from wastewater. In addition, its adsorption capacity can be further improved by the enhancement of adsorption functional groups on the surface through chemical modification.

Microalgae have been publicized for their diversified dominance responsiveness and bioaccumulation potential toward pollutants in an ecosystem. Also, algal's incredible capability as biocatalysts in environmental appliances has been well elucidated owing to their robustness and simple nutritional demand. Additionally, microalgae can deliver various collections of bio-based chemical compounds helpful for diversified applications, especially as green alternatives. The environment has been contaminated with various polluting agents; one principal polluting agent is heavy metals which are carcinogenic and show toxicity even in minimal quantity, cause unsatisfactory threats to the environmental ecosystem, including human and animal health. There is a prominent tendency to apply microalgae in the phytoremediation of heavy metals compounds because of its vast benefits, including great accessibility, cost-effective, excellent toxic metal eliminating efficiency, and nontoxic to the ecosystem. This review uncovers the most recent advancements and mechanisms associated with the bioremediation process and biosorption interaction of substantial harmful synthetic compounds processing microalgae species. Furthermore, future challenges and prospects in the utilization of microalgae in heavy metals bioremediation are also explored. The current review aims to give valuable information to aid the advancement of robust and proficient future microalgae-based heavy metal bioremediation innovations and summarizing a wide range of benefits socioeconomic scope to be employed in heavy metal compound removal in environment system.

Population growth, urbanization, and decarbonization efforts are collectively straining the supply of limited resources that are necessary to produce batteries, electronics, chemicals, fertilizers, and other important products. Securing the supply chains of these critical resources via the development of separation technologies for their recovery represents a major global challenge to ensure stability and security. Surface water, groundwater, and wastewater are emerging as potential new sources to bolster these supply chains. Recently, a variety of material‐based technologies have been developed and employed for separations and resource recovery in water. Judicious selection and design of these materials to tune their properties for targeting specific solutes is central to realizing the potential of water as a source for critical resources. Here, the materials that are developed for membranes, sorbents, catalysts, electrodes, and interfacial solar steam generators that demonstrate promise for applications in critical resource recovery are reviewed. In addition, a critical perspective is offered on the grand challenges and key research directions that need to be addressed to improve their practical viability.
