| Abstract: | In tis paper, chemical forms of beryllium in three soil and its extraction were studied. Comparison experiments of extraction of beryllium forms in raw soil and soil of beryllium added were made. The suitable extrating reagents of beryllium forms in soil were selected. The sequential extracting method of beryllium forms in soil was established. The mechanism for the extraction of beryllium and the law of distribution of beryllium forms in soil were discussed. Correlation between soil extracted available beryllium and content of beryllium absorbed by plant in pot experiment was also studied. |
