摘要：

In this study, the pollution status of heavy metals (Zn, Pb, Ni and Cr) in the sediments of the Songhua River in an urban area with petrochemical industries were assessed. Effect of temperature, reaction time, pH and nano zero valent iron dosage on Pb, Cr and Ni removal are studied. Experimental results indicated that adding the nano zero valent iron accelerates the Pb, Cr and Ni removal. The best removal efficiency of Cr reached 95.5%. The highest Pb and Ni removal is 89.63%, 96.64% when temperature is 40 degrees C, reaction time is 540 s, and nano zero valent iron is 10 g/L.
