The widespread accumulation of insecticides in water systems is a growing concern. This study reports efficient photodegradation of imidacloprid (IMD) insecticide using polyethersulfone (PES) membranes modified with iron‐doped cerium oxide (Fe‐CeO2). The work focuses on the modification of ultrafiltration polyethersulfone membranes with incremental amounts of Fe‐CeO2 photocatalysts (0.5–2.0 wt.%) using phase inversion method. An increase in Fe‐CeO2 content showed an improvement in surface roughness and porosity of membranes. Pure water flux (PWF) increased from 55.9 L m2 h−1 in M0 (PES) to 77.2 (M1, 0.5% Fe‐CeO2‐PES), 118.0 (M2, 1% Fe‐CeO2‐PES), 128.0 in M3 (1.5 wt.% Fe‐CeO2‐PES) and then decreased to 98.5 L m2 h−1 in M4 (2 wt.% Fe‐CeO2‐PES). This decrease is brought about by the high Fe‐CeO2 content, which minimizes the membranes' surface pores. Fe‐CeO2 photocatalysts are thought to give the membrane both hydrophilic and photocatalytic qualities because of their capacity to absorb light and create radical species that cause the photodegradation of IMD molecules. Consequently, under visible light irradiation, modified membranes demonstrated photocatalytic ability over IMD. Photocatalytic efficiencies of the membranes were found to be 5.2% (M0), 68.9 (M1), 75.8 (M2), 81.8 (M3), and 56.0% (M4), respectively, with M3 membranes showing the highest photocatalytic degradation efficiency and low leaching of metals. The remarkable performance observed by M3 membranes during both water filtration and photocatalytic performance may be an illustration of well dispersed photocatalyst which receives high absorption of light irradiation. Membranes with photocatalytic functionalities are tailored to exploit dual benefits of the membrane filtration and photocatalysis without compromising their original functions. However, maintaining the delicate balance of this phenomenon is still very challenging.

“…Numerous studies have reported technologies for the removal of IMI, including adsorption, , Electro-Fenton oxidation, , photocatalytic oxidation, − ferrate oxidation, , and persulfate oxidation. − Among them, persulfate-based advanced oxidation processes (AOPs) have been vastly studied for organic wastewater treatment due to the fact that the SO 4 •– generated in the persulfate oxidation process had a higher standard redox potential (SO 4 •– : 2.5–3.1 eV) and a prolonged half-life (30–40 μs) compared to • OH. − Nevertheless, considering the cost factor caused by the persulfate-based AOPs, there are still non-negligible limitations in their practical applications. In contrast, bisulfite (BS) has the advantages of low cost, low toxicity, and high activity .…”

Over the past several decades, the value of drinking water treatment residuals (WTRs), a byproduct of the coagulation process during water purification, has been recognized in various environmental applications, including sustainable remediation of phosphorus (P)-enriched soils. Aluminum-based WTRs (Al-WTRs) are suitable adsorbent materials for P, which can be obtained and processed inexpensively. However, given their heterogeneous nature, it is essential to identify an easily analyzable chemical property that can predict the capability of Al-WTRs to bind P before soil amendment. To address this issue, thirteen Al-WTRs were collected from various geographical locations around the United States. The non-hazardous nature of the Al-WTRs was ascertained first. Then, their P adsorption capacities were determined, and the chemical properties likely to influence their adsorption capacities were examined. Statistical models were built to identify a single property to best predict the P adsorption capacity of the Al-WTRs. Results show that all investigated Al-WTRs are safe for environmental applications, and oxalate-extractable aluminum is a significant indicator of the P adsorption capacity of Al-WTRs (p-value = 0.0002, R2 = 0.7). This study is the first to report a simple chemical test that can be easily applied to predict the efficacy of Al-WTRs in binding P before their broadscale land application.
