抄録: The adsorption of phenol from aqueous solution was carried out by using alginate-stabilized silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) beads as adsorbents. The resulting AgNPs and AuNPs were characterized by scanning electron microscope, UV-visible spectroscopy and Fourier transform infrared spectroscopy. Batch adsorption studies have shown that removal is dependent upon process parameters like initial concentration, contact time, pH and adsorbent dosage. The adsorption data obtained from batch studies at optimized conditions have been subjected to Freundlich and Langmuir isotherm studies. The pseudo-first-order and pseudo-second-order kinetic models were also applied to the experimental data. Phenol was effectively (90.0 +/- A 0.8 %) removed from the aqueous solution using alginate-stabilized AuNPs beads as the adsorption process. Desorption studies were made to elucidate recovery of the adsorbate and adsorbent for the economic competitiveness of the removal system. The alginate-stabilized AgNPs and AuNPs beads were found to be good adsorbents for adsorption of phenol from the aqueous solution.
