Albizia Lebbeck Leaves-Capped Silver Nanoparticles (ALLC AgNPs) were constructedusing a green and sustainable method and used as an effective adsorbent for the removal ofbutylparaben (BP) dye from an aqueous solution. The possible mechanisms for thefabrication of ALLC AgNPs were also investigated and discussed. The proposed adsorbentwas characterized and identified using FT-IR, XRD, and SEM techniques. For investigatingthe influence of affective factors like BP dye concentration, pH, adsorbent dosage, andsonication time on the removal process and achieving optimum conditions, central compositedesign (CCD) based response surface methodology (RSM) was applied. To investigate theadsorption mechanism and kinetic of the removal reaction, different isotherm and kineticmodels were used. The obtained results proved the applicability of fabricated adsorbent as anideal material for the treatment of pollutants and especially dye molecules. تفاصيل المقالة
