Green Fabrication of Albizia Lebbeck Leaves-Capped Silver Nanoparticles for Removal of Butylparaben

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