| چکیده مقاله |
| Dye-contaminated wastewater presents a significant environmental concern owing to the toxicity, stability, and persistence of synthetic dyes in aquatic ecosystems[1, 2]. Traditional treatment methods frequently exhibit low efficiency, membrane fouling, inadequate selectivity, or elevated operational expenses[3]. A hybrid composite adsorbent (P.M.C) was synthesized by integrating mesoporous silica nanoparticles with a triazine–phosphazene COF framework and polyethyleneimine functionalities. Structural analyses confirmed the formation of a hierarchical, amine-rich composite with preserved mesoporosity and favorable surface charge characteristics. P.M.C exhibited high adsorption capacities toward various dyes, including MB, NR, CR, MG, and MO, following pseudo-second-order kinetics and fitting Langmuir–Freundlich isotherms. The adsorbent showed optimal performance at near-neutral pH and excellent reusability, highlighting its potential for efficient and sustainable wastewater treatment |
