Evaluatıon Of The Performance Of Green Synthesızed Sılver Nanopartıcle Loaded Actıvated Carbon For The Removal Of Cr(Vı) Ions

The objective of this study was to evaluate the usability of silver nanoparticles loaded on activated carbon (SNP-AC) for the removal of Cr(VI) metal ions from aqueous solutions. Following the optimization of the effect of variables (batch method) including pH, contact time, initial metal concentration and amount of SNP-AC on Cr(VI) removal method, the isotherm study was carried out by taking different models into consideration. Based on difference in Cr(VI) contents (measuring by a UV–vis spectrophotometer) before and after adsorption, the removal percentage was calculated. The equilibrium experimental data well fitted to the Langmuir models with maximum adsorption capacity of 71,4 mg SNP-AC. The results of this study indicated that silver nanoparticle coated activated carbon (SNP-AC) might be a good promising alternative material for the removal of Cr(VI) metal ion owing to its high adsorption capacity in short equilibrium time.
