Antibiotic contamination in pharmaceutical wastewater poses environmental and public health risks. This study synthesized a nanocomposite ceramic adsorbent from clay, cow bone powder (hydroxyapatite nanoparticles), human hair for antibiotic removal. The exhibited high mechanical strength (3.6 bar), chemical stability, large surface area (171.32 m2 g-1). Characterization (FTIR, XRD, FE-SEM, BET) confirmed successful nanoparticle incorporation. In vertical fixed-bed column, optimal removal occurred at pH 7, 25 g adsorbent, °C, 40 min contact time. Adsorption was endothermic, following pseudo-first-order intraparticle diffusion models. retained >90% efficiency after 142 regeneration cycles, proving its durability cost-effectiveness.

Microplastics (MPs) are novel pollutants that can adsorb heavy metals in water environments and migrate together as carriers prone to aging due the light water. However, few reports have been published on synergistic behavior effects of these different types aged MPs adsorption desorption Cr(VI). Here, two MP types─polyamide (PA) polylactic acid (PLA)─were by UV irradiation, behaviors Cr(VI) were studied. The results indicated rapidly age MPs. After exposed light, their specific surface area, negative charge, oxygenic groups increased, resulting enhanced hydrophilicity. depicted a markedly capacity for compared with aged-PA > pristine-PA aged-PLA pristine-PLA. process followed Langmuir pseudo-second-order models, confirming chemical monolayer primary processes involved was more easily desorbed simulated gastric fluid environment. rate lower than pristine because stronger binding forces mainly depends mechanisms such electrostatic attraction, reduction reactions, chelation groups. This study clarifies reciprocity mechanism between provides further insights guidance controlling joint pollution metal future.

The global increase in plastic production has significantly contributed to the contamination of aquatic environments with MPs. This study examined adsorption CV dye onto PS MPs ecosystems. BBD was utilized optimize conditions and evaluate effects key independent variables on process. sorption experiments were conducted using reaction mixtures containing at levels ranging from 0.1 1.5 g/L concentrations 5 20 mg/L. pH samples adjusted range 4 10, while duration interaction varied between 10 60 min. findings revealed that optimal rate for (84.96%) achieved a level 12.5 mg/L, dosage 1 g/L, 7, an 35 In this investigation, ZP particles transitioned − 45.6 16.8 mV following CV. Furthermore, kinetics most accurately described by pseudo-first-order model, demonstrating high R2 value 0.99. Langmuir isotherm (R2 = 0.99) further confirmed presence significant interactions molecules surface sorbent, highest capacity quantified 6.25 mg/g. highlights role microplastics as carriers harmful dyes, such CV, environments. It underscores urgent need research into environmental consequences microplastic pollution development strategies mitigate their impact.
