Adsorption of 2 Chlorophenol on Activated Carbon Prepared from Orange and Banana Husk: Equilibrium and Kinetic Studies
Background and Objectives: Phenolic compounds present in many industrial effluents that classified as priority pollutants. Therefore, its treatment is necessary before discharge into the environment. The aim of this study was to assess the 2 chlorophenol adsorption by orange and banana shell activated carbon. Materials and Methods: This study was performed in laboratory at batch scale. The orange and banana peel was sun dried at 105 Co, then carbonized, crushed and sieved to particle sizes in range of 30 mesh. The effects of different parameters including contact time (10 120 min) pH (3 11) 2 chlorophenol initial concentration(10 200 mg/L) and biomass dosage (0.2 2 g/L) were studied for removal of 2 chlorophenol. All experiments were repeated twice and then adsorption isotherms and kinetics of different models were analyzed by comparing the regression coefficient and R squared (R2) Results: The results indicated that the 2 chlorophenol adsorption rate increases by increasing of contact time and adsorbent dose for both adsorbents, however, the 2 chlorophenol adsorption per each gr of adsorbnts(qe) decreased. The adsorption efficieny increased by decreasing of intial 2 chlorophenol concentration and increasing of pH. The optimum pH was 5 in 2 chlorophenol adsorption and obtained data well fitted by Langmuir Isotherm in comparison with other isotherms. It was found that the kinetics data fitted well the pseudo first order. Conclusion: According to the achieved results, it can be concluded that orange and banana shell activated carbon as an inexpensive adsorbent, had a high adsorptive potential for removal of 2 chlorophenol from water and wastewater samples.
