dc.description.abstractThe adsorption potential of animal charcoal (BC/RHA/WH composite mixture to remove Zinc (II) ions from industrial wastewater was investigated using a fixed bed column was investigated. The effects of bed height (2 - 10) cm, flow rate (5 - 10) ml/min and feed concentration (diluted in the ratio 1:1 and 1:2) on the break through characteristics were determined. The highest bed capacity of 476.2 mg/g mg/g was obtained using 10 cm bed height, 1:2 feed concentration and 5 ml/min flow rate. The results indicate that adsorption capacity increased with increase in the inlet ion concentration and bed height and decreased with increase in flow rate. Adsorption data was fitted to Adam-Bohart, Thomas and Yoon-Nelson modelsen_US
