The north most representative cinnamon soil was selected as the tested soil. The study considered the effect of dissolved organic matter on migration of Cu, Cd, Pb and Zn in soils by column experiment. Migration and transformation model was built which based on the soil solute transport model. It is important for the prediction of the temporal and spatial distribution of pollutant, and help to prevent...
The present work deals with the study of uptake behaviour of Cd(II), Pb(II), Hg(II) and Zn(II) ions by chemically synthesized poly(p-Bromoanaline) PPBrAN using batch equilibration technique with both single and binary mixtures. The PPBrAN were chemically synthesized in different HCl concentrations. The effect of the various parameters such as synthesis method, physical oxidation state of the polymer,...
Pollution property of particulates in the air and its affecting factors at the traffic crossing in Harbin were studied. PM10 in atmosphere was sampled in August 2005 near the roads of Harbin, the ions, heavy metals and carbon ingredients of PM10 were analyzed. The results showed that the proportion of the samples which didn't meet the national standard was 75%. The concentrations of SO42-, NH4+,...
Batch experiments were carried out to investigate heavy metal ions adsorption properties of steel slag, the results showed that steel slag could be used as an effective adsorbent to removal heavy metals such as Cr3+,Cu2+,Pb2+and Zn2+ from the aqueous solution. For the heavy metal Cr3+, the removal yield increased with increasing contact time and reached the equilibrium state within lh; The removal...
