| Abstract: | Strontium is among the most hazardous radioactive of fission products.The research studied the sodium alginate-CaCl2 immobilized yeast(Saccharomyces cerevisiae) cell bead characters and the adsorption ratio,adsorption quantity and equilibrium curves of static adsorption,and the chromatography parameters for packed column adsorption of strontium based on the biosorption and immobilization advantages.The results showed that the sodium alginate-CaCl2 immobilized yeast cell beads had high specific surface area ... |
| Keywords: | yeast(saccharomyces cerevisiae) immobilization adsorption packed column strontium |
