Adsorption of Cu2+ Ion in Wastewater by Using the Trass Ceramisite Coated by Metal Oxide
The trass ceramisite and ceramisite coated by iron oxide or alumina have been carried out to adsorb the copper (25mg/l) inside wastewater. The results show that the removal rate of trass ceramisite is the lowest, and removal rate of the trass ceramisite coated by alumina is the highest with the removal rate up to 67%. The optimum conditions of Cu 2+-adsorption in wastewater by ceramisite coated by alumina are as follow: pH at 6, contact time for 40min, the amount of adsorbent at 12.5g/l.
