“…The increase in ions vying for the available binding sites, which results in the saturation of active sites, can be used to explain this tendency. Similar outcomes were observed for the adsorption of La 3+ and Sm 3+ on the biomass of the fungus Penicillium simplicissimum and La 3+ and Ce 3+ on the powdered leaf of Platanus orientalis [27,28]. Table 1 lists the correlation coefficient (R 2 ) and the constants for the Langmuir, Freundlich, Temkin, and DRK models.…”

Previous studies showed that chemical modified Bacillus subtilis biomass possessed the high potential for recovery rare-earth elements, and, in this study, mathematical models were applied to explain the B. subtilis biomass La3+ and Sm3+ ions sorption capacity. The experimental isotherm data were analyzed using Langmuir, Freundlich, Temkin, and DRK equations. Both Langmuir and Freundlich isotherms models that fit the equilibrium data. Temkin model showed that it occurs physisorption. In more dilute solutions, the adsorption preference follows the order La3+ > Sm3+. With the increase in the concentration of rare-earth elements, there is an inversion in the preference for Sm3+ > La3+. The results demonstrate that the optimum model for describing the kinetics of the biosorption of both rare-earth elements is the pseudo-second-order model as well as the viability of recovering lanthanum using bacterial biomass sorbents, a practical technique.

“…The pseudo-second-order kinetic model is generally used to predict the adsorption behavior of solid biosorbents. It is assumed that the chemical adsorption mechanism is the rate-limiting aspect of the whole adsorption process [50], and that the resistance of mass transfer usually occurs in the outer layer of the biosorbent [51]. The adsorption processes of biosorbents mostly conform to the pseudo-second-order chemical reaction kinetic model, while the pseudo-order adsorption kinetic model is only in good agreement with the experimental data in the initial stage of the first step reaction [32,52].…”

Bioadsorption of Terbium(III) by Spores of Bacillus subtilis

et al. 2022

Wastewater containing low concentrations of rare earth ions not only constitutes a waste of rare earth resources but also threatens the surrounding environment. It is therefore necessary to develop environmentally friendly methods of recovering rare earth ions. The spores produced by Bacillus are resistant to extreme environments and are effective in the bioadsorption of rare earth ions, but their adsorption behaviors and mechanisms are not well understood. In this study, the cells and spores of Bacillus subtilis PS533 and PS4150 were used as biosorbents, and their adsorption of terbium ions was compared under different conditions. The adsorption characteristics of the spores were investigated, as were the possible mechanisms of interaction between the spores and rare earth ions. The results showed that the PS4150 spores had the best adsorption effect on Tb(III), with the removal percentage reaching 95.2%. Based on a computational simulation, SEM observation, XRD, XPS, and FTIR analyses, it was suggested that the adsorption of Tb(III) by the spores conforms to the pseudo−second−order kinetics and the Langmuir adsorption isotherm model. This indicates that the adsorption process mainly consists of chemical adsorption, and that groups such as amino, hydroxyl, methyl, and phosphate, which are found on the surface of the spores, are involved in the bioadsorption process. All of these findings suggest that Bacillus subtilis spores can be used as a potential biosorbent for the recovery of rare earth ions from wastewater.

“…Biosorption is a physicochemical and metabolically-independent process to remove metals selectively that includes adsorption, ion exchange, precipitation, and surface complexation mechanisms on biosorbents. 11 , 51 – 53 In a recent study, the operating cost of a hydrometallurgy plant for the American project Bear Lodge (which includes two REE mines) was estimated at USD 10.78 /kg of REO, while the biosorption process would cost USD 15/kg, with results of comparable quality (95% vs . 97% purity).…”

Replacement of conventional hydrometallurgical and pyrometallurgical process used in E-waste recycling to recover metals can be possible. The metallurgical industry has been considered biohydrometallurgical-based technologies for E-waste recycling. Biorecovery of critical metals from phosphor powder from spent lamps is an example of transition to a bio-based circular economy. E-waste contains economically significant levels of precious, critical metals and rare-earth elements (REE), apart from base metals and other toxic compounds. Recycling and recovery of critical elements from E-waste using a cost-effective technology are now among the top priorities in metallurgy due to the rapid depletion of their natural resources. This paper focuses on the perceptions of recovery of REE from phosphor powder from spent fluorescent lamps regarding a possible transition toward a bio-based economy. An overview of the worldwide E-waste and REE is also demonstrated to reinforce the arguments for the importance of E-waste as a secondary source of some critical metals. Based on the use of bioprocesses, we argue that the replacement of conventional steps used in E-waste recycling by bio-based technological processes can be possible. The bio-recycling of E-waste follows a typical sequence of industrial processes intensely used in classic pyro- and hydrometallurgy with the addition of bio-hydrometallurgical processes such as bioleaching and biosorption. We use the case study of REE biosorption as a new technology based on biological principles to exemplify the potential of urban biomining. The perspective of transition between conventional processes for the recovery of valuable metals for biohydrometallurgy defines which issues related to urban mining can influence the mineral bioeconomy. This assessment is necessary to outline future directions for sustainable recycling development to achieve United Nations Sustainable Development Goals. Graphical Abstract
