Abstract:
A pot experiment and the sequential extraction procedure of the optimized European Community Bureau of Reference(BCR) were conducted to investigate the absorption of chromium by alfalfa and the redistribution of fractions under different pH Acetic acid-Potassium acetate buffer solution.The results showed that soil chromium ion from its inactive state into effective state effect and the migration ability of chromium from soil to plant were notable promoted with adding Acetic acid-Potassium acetate solution to the soil.The migration ability of chromium ion from soil to plant was also different under different pH Acetic acid-Potassium acetate buffer solution.In the test range，the accumulation of chromium from soil to plant were a control sample of 3 times when the pH was 5.8，the content value was 37.55 mg/kg，the enrichment coefficient reached 0.22.
