| 摘 要： | 通过在不同浓度的酸性、碱性、盐性以及有色重金属盐溶液中分别测定人工钠基膨润土的膨胀容,分析了不同溶液对人工钠基膨润土膨胀容的影响。结果表明：酸性和盐性溶液能明显降低人工钠基膨润土的膨胀容,影响人工钠基膨润土的防渗效果;人工钠基膨润土有较强的耐碱性,其在碱性溶液中防渗效果几乎不受影响;且人工钠基膨润土在一定程度上有吸附重金属离子的作用。

| Abstract: | The influence of different solutions on swelling capacity of artificial Na-bentonite was analyzed by testing the swelling capacities in different concentrations of acidic,alkaline,salt,and nonferrous heavy metal solutions,respectively.The results showed that acidic and salt solutions could significantly decrease swelling capacity of artificial Na-bentonite,and influence impermeable effect of artificial Na-bentonite.The artificial Na-bentonite has good alkali resistance,its impermeable effect was not affected by alkaline solution.And it could adsorb heavy metal ions to a certain extent. |
