Abstract
In point of recycling wastes, batch test was conducted to examine the neutralization and Fe removal from laboratory wastewater using wastes. Oyster shell and slag had a buffer capacity to neutralize an acidic wastewater but tire rubber didn't. With increasing reaction time, dosage and agitation speed, Fe was well removed by wastes. As a result on the experiments of Freundlich isotherm, the adsorption intensities(1/n) were 0.32∼0.46 and the adsorption capacities(k) were 4.3∼4.6 for removing Fe from laboratory wastewater by wastes. In view of these results, it was estimated that wastes containing the similar compositions as these could utilize the neutralization and adsorption of heavy metals in laboratory wastewater.
