Abstract BACKGROUND The heterogeneous photo‐Fenton process demands stable and efficient materials as catalysts to decompose hydrogen peroxide generate reactive oxygen species promote the degradation of organic contaminants in wastewater. In this study, catalytic activity an iron mining residue (IMR) was investigated for anticancer drugs 5‐fluorouracil (5‐FU) cyclophosphamide (CP) present hospital wastewater (HW). RESULTS High efficiency observed 5‐FU (>99%) CP (>95%) after 45 min at pH 2.5 using 1 mmol L −1 H 2 O , 0.3 g IMR water. generation hydroxyl radical, especially under solar irradiation, indicated role catalyst generating oxidizing species, which confirmed by drastic decrease presence tert‐butyl alcohol, transformation products identified during process. showed stability maintained >95% removal efficiencies over three reuse cycles with negligible leaching (< μmol ). For HW, application a vermifiltration pre‐treatment reduced TOC levels from 129 mg 21.9 turbidity 64 NTU 12 NTU, enabling >80% 90 optimized conditions (0.3 IMR, 3 H₂O₂, irradiation). CONCLUSION It can be concluded that presents high real highlighting its potential cost‐effective sustainable treatment © 2025 Author(s).

This study investigates biomimetic sensors for the detection of methotrexate contaminants in environmental samples. Sensors inspired by biological systems are focus this strategy. Methotrexate is an antimetabolite that widely used treatment cancer and autoimmune diseases. Due to widespread use its rampant disposal into environment, residues drug regarded as emerging contaminant huge concern, considering exposure has been found lead inhibition some essential metabolic processes, posing serious risks humans other living beings. In context, work aims quantify through application a highly efficient electrochemical sensor constructed using polypyrrole-based molecularly imprinted polymer (MIP) electrodeposited cyclic voltammetry on glassy carbon electrode (GCE) modified with multi-walled nanotubes (MWCNT). The polymeric films were characterized infrared spectrometry (FTIR), scanning electron microscopy (SEM), (CV). analyses conducted differential pulse (DPV) yielded limit 2.7 × 10-9 mol L-1 methotrexate, linear range 0.01-125 μmol L-1, sensitivity 0.152 μA L mol-1. results obtained from analysis selectivity proposed incorporation interferents standard solution pointed signal decay only 15.4%. findings show promising suitable quantification
