Study on Tdsorption of Heavy Metalion in Metallurgical Wastewater by Montmorillonite

Abstract:

In this study, the sorption of single heavy metal (Cu2+, Pb2+ and Zn2+) and multiple heavy metals in simulated metallurgical wastewater by montmorillonite was investigated. The effect of adsorption time and temperature conditions, etc. on the adsorption was also studied. The results showed that in the same concentration of adsorbent dosage, removal rate of single heavy metal is the highest (99.9%, 88.1% and 98.3%) when the concentration of Cu2+, Pb2+ and Zn2+ is 50 mg/L, 20mg/L and 100mg/L, respectively. The adsorption of multiple heavy metals in simulated metallurgical wastewater is the highest in 4 hours at 20°C. The adsorption capacity is in order of Pb2+≈Zn2+>Cu2+>Cd2+ and removal rate is 90.8%, 87.3%, 70.0% and 51.6%, respectively.
