| 摘 要： | 本文研究了溶液中金属离子和pH对红壤吸附SO_4~(2-)的影响。实验结果表明,溶液pH降低,红壤吸附SO_4~(2-)的量增加;溶液中金属离子种类不同,红壤吸附SO_4~(2-)的量差异很大。其次序为Al~(3+)>Zn~(2+)>Na~+。实验结果也表明,当溶液中有Al~(3+)Zn~(2+)离子存在时吸附的SO_4~(2-)较有Na~+离子存在时吸附SO_4~(2-)难被水解吸下来。

| Abstract: | The effect of metal ions and pH on sulfate adsorption in Red Soil was investigated. The results obtained showed that sulfate adsorption increased with the decrease of solution pH for different metal ions in the solution with the same SO42- concentration following the order, Al3+>Zn2 + > Na + . On the other hand,SO42- adsorbed from solution with Al3+ and Zn2+ was more difficult to be desorbed by elution with H2O than that adsor-bed With Na+. |
