Cu II Removal from Industrial Wastewater Using Low Cost Adsorbent

Abstract

Study the possibility of utilization of waste tires rubber ash (WTRA) as a low-cost adsorbent and are available as a type of solid waste for the removal of copper ions from industrial wastewater. Depending on batch adsorption experiments, the effect of different parameters including pH, adsorbent dosage WTRA, contact time, initial concentration of the ion and shacking speed were studied. Results showed that the highest removal Cu+2 ions was 97.8% at pH equal to 6, 120 min contact time, dose WTRA 1.5 g/L, shacking speed 150 rpm. The experimental data were analyzed using the Freundlich and Langmuir isotherm models showed great compatibility with Langmuir model (R2=0.923). Adsorption kinetics was studied and the data was showed agree with Pseudo-first-order equation where the value of (kt=0.5115/min). The study also showed the possibility of using WTRA efficiently as adsorbent and low cost in the removal of copper ions from industrial waste water. DOI: http://dx.doi.org/10.25130/tjes.24.2017.17
