    并分析了流速、進水中重金屬離子( hg2 + )的濃度以及原水中常見的陽離子( ca2 + 、 mg2 + )和陰離子( cl 、 so42 )對弱堿性陰離子交換樹脂去除飲用水中微量重金屬離子的影響。
  • Highlights of the applied research in 1997 included the analysis of volatile organics with canister sampling , carbon speciation of air particulates , semi - volatile organic pollutants in water , and ultra - trace heavy metals in sea water with on - linechelation

  • 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。
  • By means of static and dynamic experiments , lots of research on the effect of micro - quantity heavy metal ions ( hmi ) removal by weakly basic anion exchange resins ( wbaer ) from drinking water ( dk ) with alkali metals , alkaline - earth metals and anions at high concentration , has been done
    本文采用靜態和動態兩種試驗方法,對弱堿性陰離子交換樹脂在堿金屬、堿土金屬離子以及陰離子相對較高濃度的背景下去除飲用水中微量重金屬離子(以hg2 +為研究處理對象)的效果進行了大量試驗研究。
  • 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。
