摘要
介绍了盐水中Ca2+、Ma2+、SO2-4、SiO2-3及Fe3+、Al3+、Si2+、Ti2+、S2-等阴阳离子对离子膜表面的污染情况及这些离子对离子膜性能的影响,并提出了延长离子膜寿命的方法。
The impurity ions on ion exchange membrane pollution and properties impact were introduced, which include anions, cations and elements such as Ca2＋ Mg2＋ SO＋-, SiO＋-and Fe3＋,A13＋,Si,Ti S etc. in the brine.The method extend the life of the ion-exchange membrane were put forward.
