“…The phosphate removal efficiency was 85.3% with the addition of 0.1 g FeATP and 97.8% with 0.3 g FeATP, after which point the removal efficiency remained almost unchanged with the continued addition of FeATP. This observation indicates that Fe-modified ATP displayed a stronger phosphate adsorption ability because Fe was more uniformly dispersed on the surface of ATP (Zhu et al 2022). Moreover, the pore size of the modified FeATP was contracted relative to that of ATP, and the specific surface area increased, resulting in a larger contact surface with phosphate.…”

Magnetite/zirconium-comodified attapulgite (Fe/ZrATP) acting as a novel phosphorus (P) sorbent was synthesized, characterized and applied to control P in an aquatic environment. Batch experiments demonstrated that at an adsorption dose of 0.2 g, 97.8% of the phosphate was rapidly sequestered from aqueous solution within 24 h, and the composite reached a maximal sorption capacity of 3 mg/g. The adsorption performance of the adsorbent Fe/ZrATP was minimally affected by changes in the initial pH (pH = 2–11). In addition, Fe/ZrATP presented excellent selectivity for phosphate when coexisting ions that often occur in water bodies were present; the solution ionic strength exerted little influence on phosphate sorption behavior. Adsorption and desorption experiments indicated that the removal of phosphate was mainly due to adsorption. The Fe/ZrATP adsorption isotherm was fitted to the Freundlich adsorption model. Moreover, the composite demonstrated excellent recyclability performance. The P adsorption mechanism of Fe/ZrATP involves electrostatic interactions, ligand exchange and surface precipitation. Our findings indicated that the separable Fe/ZrATP demonstrated high efficiency and sustainable phosphate removal, which is promising in phosphate removal and recovery applications

“…Zhu's group obtained a Fe 3 O 4 @tourmaline (Tml) catalyst by depositing the Fe 3 O 4 on the surface of Tml. [136] From Figure 7a-c, the SEM, transmission electron microscope (TEM), and HR-TEM showed the successful synthesis of Fe 3 O 4 @Tml. Under the stirring with the 300 rpm, the leached Fe 2þ and reduced Fe 3þ could reach to 53.69 AE 0.86 μM (Figure 7d) and 1.36 AE 0.00 μM (Figure 7e) in Fe 3 O 4 @Tml, respectively.…”

Photocatalysis‐self‐Fenton system (PSFs), which integrates photocatalysis with Fenton technology, is investigated thoroughly in wastewater treatment due to the virtues of no addition of H2O2 and accelerated circulation of Fe2+/Fe3+. Several kinds of materials that mainly include metal‐free graphite carbon nitride (g‐C3N4), metal oxides (Fe3O4), and metal sulfide (CdS, FeS2) have demonstrated extensive development potential. Nevertheless, most of the developed catalysts are unable to satisfy the requirements of PSFs. Therefore, a comprehensive review committed to the materials and modification methods in PSFs is put forward. First, the concrete mechanism of PSFs from two aspects of photocatalysis and Fenton reaction is discussed. Second, the properties, modifications (morphology modulation, heterojunction construction as well as doping), and applications (contaminants degradation and disinfection) of the promising catalysts are emphasized. Finally, the novel directions for future research in PSFs are looked forward to. This review opens up a new horizon for enhancing the practical application of PSFs in future.
