Experimental study reveals efficient meropenem antibiotic removal using functionalized rice husk in aqueous solution, highlighting a sustainable approach for wastewater remediation.

Key Points

To synthesize and evaluate rice husk functionalized with Mg/Fe-layered double hydroxides as an effective adsorbent for extracting meropenem antibiotic from water.
Conducted batch adsorption experiments across various solution pH values and M2+/M3+ ratios.
Modeled experimental equilibrium and kinetic data using Langmuir, Freundlich, and pseudo-second-order equations.
Synthesized the optimal Mg/Fe-LDH adsorbent at pH 9 with an M2+/M3+ ratio of 0.5, achieving the smallest particle size of 11.1 nm.
Demonstrated high equilibrium fitting with both Langmuir (R² = 0.984) and Freundlich (R² = 0.993) isotherm models, yielding a maximum adsorption capacity of 43.3 mg/g.
Observed adsorption kinetics that adhered closely to the pseudo-second-order kinetic model.
