Abstract

A new composite adsorbent was developed in this study to remove the heavy metals from the aqueous solution. Flyash, activated carbon (regenerated from the water filter system installed at homes) and iron oxide were mixed in 2:1:1 and then followed several treatment processes to form composite adsorbent. Batch study was performed to investigate the effect of adsorption parameters (pH, contact period and adsorbent dose) on the removal efficiency. The adsorption process was found to be much more dependent on pH and dose of adsorbent while contact period did not play a significant role. The pH between 7 and 9 was most favourable for adsorption in this study for all the selected heavy metals. At a minimum contact period of 15 min, there was a removal efficiency of around 70-80% while the equilibrium period was in the range of 60-120 min. The adsorption capacities for the selected heavy metals were in decreasing order of Fe (12.04 mg/g) > Zn (11.425 mg/g) > Pb (11.206 mg/g) > Cu (0.69 mg/g). On the observation of the result of this study, the prepared adsorbent has the potential to remove heavy metals from aqueous solution.
