弱堿性陰離子交換樹脂Determination for strong - base group, weak - base group and weak - acid group exchange capacity of acrylic type anion exchange resins
丙烯酸系陰離子交換樹脂強堿基團弱堿基團和弱酸基團交換容量測定方法And factors, such as flow velocity, the concentration of hmi in influent water and usual cations ( ca2 +, mg2 + ) or anions ( cl -, so42 - ) in raw water, which can influence the effect of hmi removal by wbaer from dk has also been discussed
並分析了流速、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。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。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
本文採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。In a word, wbaer can effectively remove micro - quantity hmi from dk with alkali metals, alkaline - earth metals and anions at high concentration. on the basis of lots of regeneration experiments of wbaer ( d301g ), the best regeneration manner ( regurgitation regeneration ), the optimal regeneration agents ( h2so4 and naoh ) and the optimum operating parameters of regeneration are obtained
論文進而對d301g型弱堿性陰離子交換樹脂進行了再生試驗研究,確定了最佳再生方式(逆流再生) ,最佳再生劑( h2so4和naoh )以及酸液再生時的最佳濃度范圍( 2 % 4 % )和最佳流速范圍( 3 4m / h ) ;並通過正交試驗確定了逆流再生過程中的最佳運行參數組合。Column is used for normal phase, weak anion - exchanger and specific separation in reversed phase, especially useful for separations of carbohydrates and sugars
