Ce(III) nanocomposites by partial thermal decomposition of Ce-MOF for effective phosphate adsorption in a wide pH range

Phosphate Elimination and Recovery Lightweight (PEARL) membrane: A sustainable environmental remediation approach

“…However, there are several practical drawbacks to using many nanomaterials for large-scale phosphate remediation. In order to treat a problem of this magnitude, the solution must be easily manufacturable, which challenges a number of complex nanostructures (19)(20)(21).…”

Photocatalytic Easy Recovery of Orthophosphates Contaminants in Water Using Amberlite‐732 Cationic‐Resin Exchanged by Ce3+and Ce3+‐Au3+ Species

“…For all catalysts, first photopeak with the lowest binding energy (BE), observed at 528.5-529.8 eV (� 0.1 eV), was related to O 2À lattice oxygen (noted O I ); this position is close to that reported in the literature. [20,28,29] The second O1s photopeak, observed between 531.8 and 532 eV (� 0.1 eV), was assigned to adsorbed-oxygen species at the surface associated to hydroxyls species OH À (O II ). The third peak observed only for Ce-Au-Amb-Ar with the highest BE, located at 533.5 eV (� 0.1 eV), was related to the surface adsorbed oxygen of physisorbed water (O III ), according to data provided by literature.…”

“…Cerium based-catalysts were often used as an adsorbent for the phosphate recovery. Thus, Jiaojie et al [20] reported a good phosphate adsorption capacity (189 mg.g À 1 in final adsorption) with their Ce-MOF metallo-organic framework; while Su et al [21] used CeÀ Zr binary oxide as an efficient nano-adsorbent for phosphates recovery from water with the final phosphates adsorption capacity equal to 112.23 mg.g À 1 . Some ceriumbased materials were studied in catalytic reduction and photocatalytic degradation by oxidation of some large molecule organic pollutants according to, [22,23] their most relevant results show that the cerium oxide choice may be very interesting.…”

Calcined Ni–Al Complex Hydroxide and Its Use for the Removal of Phosphate Ion from Aqueous Solution

“…C e /q e = 1/W s a + C e /W s (5) where C e is the equilibrium concentration (mg/L), q e is the amount adsorbed at equilibrium (mg/g), and W s and a are the Langmuir constants related to the monolayer adsorption capacity and the energy of sorption, respectively, and log q e = log k + (1/n) log C e (6) where k and n are the Freundlich constants related to the adsorption of the adsorbent and the intensity of adsorption, respectively. Table 3 exerts the Langmuir and Freundlich constants for the phosphate ion adsorption.…”

“…Interestingly, metal (hydr)oxides have been considered useful for adsorbing phosphate ion from aquatic ecosystems, owing to their unique physicochemical properties and nontoxic characteristics. [5][6][7] In addition, calcined metal (hydr)oxides are promising adsorbents for the removal of the phosphate ion because they possess a permanent, positive layer charge (and a high specific surface area) 8,9) or a unique memory effect property. 10) The unique memory effect property facilitates rebuilding of the original structure when placed in contact with anions in aqueous solution.…”
