영문 초록

Tnis study was has been performed to evaluate the possibility of utilizing stone powder sludges from stone quarry and manufacturing plant as absorbents for heavy metals in industrial wastewater. The stone powder sludges from stone quarry (IS-01) have the most effective adsorption capacity (above 95% of initial concentrations) under the given experimental conditions of reaction times (Pb: 15 min, Cu: 2 hr, Zn: 48hr), initial acidity of solution (pH>3) and dosage (sludge/liquid ratio: 0.02). The stone powder sludges from manufacturing plant (CW-01) show rlatively high adsorption capacity (about 95% of initial concentrations) only for Pb with a reaction times of 12 hours, initial acidity of solution (pH>3) and dosage (sludge/liquid ratio : 0.02). The stone powder sludges (IS-01) from stne quarry having relatively excellent adsorption capacity under the given experimental conditions show their potential utilization as heavy metal adsorbents.
