The escalating prevalence of emerging contaminants, notably pharmaceutical and personal care products (PPCPs), poses a significant threat to global freshwater reservoirs, environmental equilibrium, human well-being. Trace amounts these micropollutants persist within aquatic environments, posing challenges in their detection, analysis, wastewater remediation using conventional approaches. Enhanced tertiary treatments (ETTs), encompassing methods such as adsorption on activated carbon (AAC), advanced oxidation processes (AOP), membrane separation process (MSP), have been introduced address challenges. This review underscores the pressing necessity for economical efficacious alternatives, with particular focus polymeric technology membrane-based treatment. approach demonstrates cost-effectiveness, facile production, excellent pollutant selectivity. Furthermore, paper explores viability utilizing agricultural waste an alternative adsorbent material adsorption-membrane hybrid systems. Introducing innovative approach—adsorption-membrane waste—this advances beyond existing literature. By leveraging alongside unique attributes adsorbents, this strategy aims enhance efficacy Noteworthy its comprehensive exploration precursors derived from waste, presents novel promising avenue treatment advancement.

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.

Adsorption and Desorption Behavior of Cr(VI) on Two Typical UV-Aged Microplastics in Aqueous Solution

Langmuir, Год журнала: 2024, Номер unknown

Опубликована: Дек. 16, 2024

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.
