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
試驗中通過改變流速（通過離子交換柱） 、進水中重金屬離子（ hg2 + ）的濃度以及向原水中引入天然水體中常見的陽離子（ ca2 + 、 mg2 + ）和陰離子（ cl 、 so42 ）等方法，比較了弱堿性陰離子離子交換樹脂和陽離子交換樹脂對飲用水中微量重金屬離子（ hg2 + ）的去除效果。 -
The results show that when the concentration of hmi ( hg2 + ) in influent water is every low, the effect of hmi removal by wbaer from dk is much better than cations exchange resins. with cations ( ca2 +, mg2 + ) at high concentration in raw water, wbaer has better selectivity to hmi in water, however the selectivity of cations exchange resins is worse. the anions in raw water such as cl - which is able to react with hmi can make cations exchange resins lose the capability of hmi removal, but it has no effect on wbaer ( d301g )
結果表明：當進水中重金屬離子（ hg2 + ）濃度較低時，弱堿性陰離子交換樹脂對飲用水中hg2 +的去除效果要明顯優于陽離子交換樹脂；當原水中含有相對較高濃度的陽離子（ ca2 + 、 mg2 + ）時，弱堿性陰離子交換樹脂對水中的重金屬離子具有很高的選擇去除性，而陽離子交換樹脂的選擇去除性卻很差；天然原水中能與重金屬離子（ hg2 + ）發生絡合反應的陰離子（如： cl ） ，可以使陽離子交換樹脂喪失了對水中微量重金屬離子（ hg2 + ）的去除作用，而對弱堿性陰離子交換樹脂（ d301g型）去除水中微量hg2 +的影響卻很小。 -
There are also indications that these materials and other similar derivatives of the asphaltenes, especially those containing such functions as carboxylic or hydroxyl, readily exchange cations and could well compete with synthetic zeolites
另有跡象表明，這些物質和瀝青質的其它類似衍生物，尤其是具有諸如羧基和羥基功能的物質，能夠迅速地交換陽離子，並且同沸石形成有力抗衡。 -
This climate make latosol usually as acidic, low levels cation exchanges capacity and low lever base cations, high levels of exchange al, with a high potential for leaching of plant nutrients
這種氣候條件使磚紅壤成為強酸性土壤，陽離子交換量和鹽基飽和度低，鋁飽和度高，化肥通過淋溶損失過程就更為突出。 -

Montmorillonite ( mmt ) clay is an important class of lamellar inorganic compounds, contains negatively charged layered silicates, which are bonded with metal cations such as na + or ca2 + by ionic bonding. whose interlayer spacing can be modified by cation exchange. when the mmt is exchanged with cations, its inner layer spacing becomes large enough to be penetrated by a monomer
蒙脫土（ montmorillonite ， mmt ）是一種天然礦物，具有層狀結構，層間靠吸附陽離子如na ~ + 、 ca ~ （ 2 + ） 、 mg ~ （ 2 + ）等來維持電荷平衡，這些離子可與其它陽離子進行交換，使有機單體分子進入層間，聚合后即可形成有機無機納米復合材料。 -
