Abstract :
The process and action mechanism of the copper wastewater adsorption accomplished by ferric salt and cerous salt modified water granulated slag were studied in this paper. Results showed that under the conditions of room temperature of 20°C, dosage of 6g/L, pH 7, reaction time of 60min to treat 100 mL 20mg/L copper wastewater, the removal rate reached 93.64%.The adsorption of modified water granulated slag to copper fits the Temkin adsorption isotherm best and the result of linear transformation of adsorption isotherm is qe=20.711nCe-4.2413, R2 = 0.9531.
