Abstract
Anion-exchange properties of plant root surfaces were demonstrated by using negatively charged anion dyes. The site of the positive charges may be amino groups which become positively charged in the presence of hydrogen ions but are neutralized under alkaline conditions.
摘要
植物根表面的阴离子交换特性可以通过使用带负电荷的阴离子染料来证明。正电荷的位置可能是氨基，在氢离子存在下带正电荷，但在碱性条件下被中和。
