Abstract Here, porous carbon (PC) and ZnO nanorods@PC (ZnO-NR@PC) composite derived from orange peel (OP) have been synthesized via a simple carbonization process. The prepared materials characterized by XRD, FT-IR, TEM, BET analysis. adsorptive properties of the PC ZnO-NR@PC investigated toward methylene blue (MB) crystal violet (CV) cationic dyes their aqueous solutions. adsorption studies concluded that maximum efficiency was achieved after 90 min in basic conditions (pH = 10). Langmuir, Freundlich, Dubinin–Radushkevich (D-R), Temkin non-linear isotherm models were applied to fit experimental data. MB CV OP is fitted with Freundlich model, both Langmuir model. estimated capacity 74.45 74.89 mg/g, respectively. calculated free energy D-R indicates MB, dye molecules OP, PC, may be physical. kinetic revealed onto pseudo-second-order On otherhand, thermodynamic confirmed an endothermic spontaneous Furthermore, displayed high stability overall removal about 90% five cycles. mechanism proposed controlled electrostatic bonding, π-π interactions, ion exchange. results indicated potential ability OP-derived carbons as adsorbents for media.

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.
