Adsorption of lead and copper ions from aqueous effluents on rice husk ash in a dynamic system

Adsorption of lead and copper ions from aqueous effluents on rice husk ash in a dynamic system

This study evaluated the kinetic adsorption of Pb and Cu ions using rice husk ash as adsorbent in a fixed bed. The maximum adsorption capacities obtained for lead and copper ions in the fixed bed were 0.0561 and 0.0682 mmol/g (at 20 ºC), respectively. The thermodynamic studies indicated that the lea...
