To achieve the resource utilization of iron ore tailings (IOTs), two different IOTs were investigated as sustainable adsorbents for ciprofloxacin (CIP) removal from aqueous systems. Through systematic batch experiments, key adsorption parameters including initial pH, adsorbent dosage, contact time, ionic strength, and temperature comprehensively evaluated. The results showed that CIP by remained relatively stable across a broad pH range (2–10), with maximum capacities 5-IOT 14-IOT observed at values 10.1 9.16, respectively. Competitive ion experiments revealed gradual decrease in capacity increasing strength (Na⁺, Mg2⁺, Ca2⁺). Thermodynamic analyses indicated an inverse relationship between temperature, yielding (Qmax) 16.64 mg/g (5-IOT) 13.68 (14-IOT) 288.15 K. Mechanistic investigations combining material characterization modeling identified exchange predominant interaction mechanism. Notably, trace elements (Cd, Co, Cr, Cu, Fe, Ni, Pb, Zn) released during leaching tests, concentrations consistently below environmental safety thresholds. A back-propagation artificial neural network (BP-ANN) optimized architecture (8-11-1 topology) demonstrated high predictive accuracy (MSE = 0.0031, R2 0.9907) behavior. These findings suggested cost-effective, environmentally compatible remediation, offering dual advantages pharmaceutical pollutant industrial waste valorization.

Water pollution, especially by heavy metals, continues to pose significant challenges, emphasizing the urgency develop sustainable processes remove pollutants while developing materials derived from renewable sources. In present research, a nanoscale adsorbent was prepared cadmium (Cd(II)) ions wastewater hybridizing zeolitic imidazolate framework-8 (ZIF-8) with cellulose nanocrystal (CNC). The nanohybrid exhibited an interconnected structure in which ZIF-8 particles were connected each other via CNC nanoneedles. hybridization of caused enhancement adsorption performance fabricated compared pure ZIF-8, increasing its capacity nearly 36%. ZIF/CNC followed Langmuir isotherm model and pseudo-second-order kinetics models, remarking homogeneous onto surface ZIF/CNC, where chemisorption controlled rate adsorption. thermodynamic study uncovered that is spontaneous, endothermic, entropy-governed as randomness increased at solid–liquid interface. Additionally, influence operating variables, such temperature, dosage, pH, ionic strength, studied mimic capabilities real conditions. Accordingly, optimum conditions found be 45 °C pH = 7 dosage 0.4 g/L for adsorbent. Moreover, multimetal solution showed can various including Cd(II), Fe(III), Cu(II), Pb(II) simultaneously. Finally, regeneration confirmed great potential nanohybrid, retained 94% initial after 5 consecutive adsorption/desorption cycles.

Tetracycline (TC) and sulfamethoxazole (SMZ) are common antibiotics utilized in human veterinary medicines to overcome bacterial infections. However, due their poor metabolism, they can easily be excreted into wastewater or sewage, leading bioaccumulation posing a risk the local environment. This research studied removal of SMZ TC using novel Fe-BTB MOF. The results showed that MOF achieved excellent adsorption capacities 649 276 mg g−1 for TC, respectively, within 1 h. kinetics equilibrium data correlated well with pseudo-second-order Sips models, suggesting favourable chemical over Adsorption experiments, spectroscopic findings, theoretical calculations suggest π-π stacking, electrostatic, hydrogen bond interactions played main role mechanism. regeneration was satisfactory its use treating antibiotic-contaminated wastewater, allowing reuse at least four cycles. Furthermore, water samples from different sources (tap, streams, sea, lake) were also used confirm adsorptive performance this practical application.

In this study, we investigated the interactions between titanium dioxide (nTiO2) and zinc oxide (nZnO) nanoparticles polyethylene microplastics (MPs) with respect to their adsorption subsequent desorption in aquatic media. Adsorption kinetic models revealed rapid of nZnO compared nTiO2, while nTiO2 was adsorbed a greater extent – four times more (67%) on MPs than (16%). The low can be explained by partial dissolution from form Zn(II) and/or aqua-hydroxo complexes (e.g. [Zn(OH)]+, [Zn(OH)3]−, [Zn(OH)4]2−), which were not MPs. isotherm indicated that process is controlled physisorption for both nZnO.
