絡陽離子 的英文怎麼說
中文拼音 [làoyánglízi]
絡陽離子
英文
complex cation-
The samples of pmn - pt have been dissolved by thick vitriol. now a convenient chemical titration analysis method was proposed to make analysis of the cations in the system
對煅燒后的樣品進行溶解,對其中的陽離子通過絡合滴定等方法來進行定量分析。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。In this article the chelating precipitation method and the converting precipitation method were chosed to synthesis zno nanoparticles on the basis of the theory of synthesis of nanoparticles by precipitation. uniform and dispersed zno nanoparticles were prepared by the two methods because zn2 + of conformation crystal was flee slowly and the supersaturation was well controlled. the problem which zno nanoparticles are wide size and agglomerative was solved
本文根據均相沉澱法合成納米粒子的原理,採用絡合沉澱法和沉澱轉化法合成納米氧化鋅。這兩種方法利用溶液中的構晶陽離子zn ~ ( 2 + ) ,緩慢地釋放出來,有效地控制了溶液中的過飽和度,可以得到粒徑均勻、分散的納米氧化鋅,解決現有制備工藝中納米氧化鋅粒徑分佈寬、易團聚的問題。The method of ehminate common eight cation inferference in compleximetry macro zn
絡合滴定中排除常見八種陽離子干擾的方法Least sweep voltammetry method was employed to study h2po2 - anodic oxidation and ni2 + cathodic reduction in electroless nickel plating solutions containing different complexing agents
運用線性電位掃描法,研究了含有不同絡合劑的化學鍍鎳溶液中鎳離子陰極還原行為和次磷酸鹽陽極氧化行為。It has draw more and more attention of scientists with the prospection use in matieral chemistry, coordination chemistry and biochemistry. by using resorcinarene as framework of supramolecular construction, we studied the single crystal structure by evaporation of acetone with the exist of a little water molecular and found that under several weak interactions, a novel nano - one - dimention supramolecular tube was abtained
杯芳烴是繼冠醚、環糊精以後的第三代主體分子,它兼有絡合陽離子與中性小分子的功能,在材料化學、配位化學、生物化學等領域表現出潛在的應用前景與研究價值,因此吸引了越來越多的化學工作者的注意。分享友人
