| 英文摘要 | The influence of rare earth elements ( rees) on soil environment has more close relationship with bound fractions than total contents. acid digestion and a sequential extraction procedure were employed to evaluate the total contents and fractions of rees in soil, respectively, then the contents of rees in soil samples and fractions extracted were determined by inductively couple plasma mass spectroscopy. results showed that the contents of rees in the soil samples sampling from baotou industry areas were in the range of 200 - 1418 mg/kg, and light rees were much higher than heavy rees. the recovery ratios of the sum of fractions to total content of rees were in the range of 88. 2% - 110%, which indicated the sequential extraction method was suited to quantify the fractions of rees in soil. residual fraction of rees was the primary form, which was in the range of 33% - 80%; the percent of crystalline ferromanganese oxyhydroxides fraction, adsorbed in humic material and amorphous oxides fraction, exchangeable and carbonates fractions was 10% - 31 %, 5. 0% - 18% and 4. 0% - 23%, respectively; fraction coprecipitated with amorphous ferromanganese oxyhydroxide was less than 3%. the effects of sampling sites and rees properties on contents and soil properties on the distribution of fractions were discussed. |
