By varying flow velocity and the concentration of HMI (Hg2+) in influent water and adding usual cations (Ca2+, Mg2+) or anions (Cl-, SO42-) into raw water, the effects of HMI removal by WBAER and cations exchange resins from DK have been contrasted.

• 试验中通过改变流速（通过离子交换柱）、进水中重金属离子（Hg2+）的浓度以及向原水中引入天然水体中常见的阳离子（Ca2+、Mg2+）和阴离子（Cl－、SO42－）等方法，比较了弱碱性阴离子离子交换树脂和阳离子交换树脂对饮用水中微量重金属离子（Hg2+）的去除效果。
