Abstract

Background and Objective: 2, 4 dinitrophenol is observed in sewage produced from chemical and petrochemical industries. Contamination of drinking water with these pollutants causes toxicity, health problems and change in taste and odor. The present study was developed to evaluate the efficiency of removal 2, 4-DNP through dried sludge adsorbent and modified calcium chloride sludge adsorbent. Materials and Methods: At first, sludge was dried at temperature of 60 ° C. Next, CaCl2 was used to improve adsorption capacity. The removal efficiency of 2, 4 dinitrophenol were determined by HPLC at wavelength of 360 nm. The effects of influencing factors including pH, initial pollutant concentration, contact time, and adsorbent dose were examined. Results: The optimum pH of adsorption for both adsorbents was found to be 7. The optimum concentration of 2, 4-DNP was 10 ppm. The results obtained from the present research showed that the removal of the contaminant using dried and modified sludge sorbent was increased from 72. 6% to 86% at a dosage of 1. 5 g. The adsorption kinetics were fitted with the pseudo second order kinetics model for both adsorbents. The isotherm data also showed that the adsorption of this pollutant on both adsorbents is fitted with the Freundlich model. Conclusion: Results obtained from the present study indicated that the efficiency of the modified sludge ash is more than the non-modified sludge in 2, 4 dinitrophenol removal. This can reduce adsorbent consumption in industrial treatment plants.
