Research on the Accumulation Law of Copper in Corn

WANG Zheng-fan(Department of Chemistry and Chemical Engineering,Weinan Teachers College,Weinan,Shaanxi 714000)  
[Objective] The purpose was to thoroughly understand the accumulation law of copper in corn.[Method] Through the experiment of simulative wastewater pollution on self planted corn,the transfer and accumulation condition of heavy metal copper in wastewater-soil-corn was researched.[Result] The simulative wastewater pollution hadn't caused obvious appearance and shape pollution on the normal growth of corn.The copper content in corn in polluted area was significantly higher than that in non polluted area.Corn significantly absorbed heavy metal copper during its growth course,but its adsorption intensities in different growth periods were different.The transfer and accumulation sequence of copper in the various parts of corn was root,stem node,stem,seed and leaf.The copper content in seeds of matured corns in polluted area was very low,their seeds were edible and that in their roots was very high.[Conclusion] The research provided a new method for purifying the pollution of heavy metal copper element in soil.
