The objective of this study was to assess and compare the usability of silver and palladium nanoparticles loaded on activated carbon (Ag NPs-AC and/or Pd NPs-AC) for the removal of Methylene blue (MB) molecules from aqueous solutions. Following the optimization of the effect of variables (batch method) including pH, contact time, initial dye concentration and Ag NPs-AC and Pd NPs-AC amounts on MB removal method the kinetic and isotherm studies have been carried out. Based on difference in MB contents (using a UV–vis …
