離子交(jiao)換樹(shu)的物理結構

一些不帶交(jiao)(jiao)換(huan)功能團的(de)(de)大(da)孔(kong)型(xing)(xing)樹(shu)脂也能夠吸(xi)附、分(fen)離多(duo)種(zhong)物質(zhi)，例如(ru)化工廠廢(fei)水(shui)中的(de)(de)酚類物。大(da)孔(kong)樹(shu)脂內部的(de)(de)孔(kong)隙又多(duo)又大(da)，表面積很大(da)，活性中心多(duo)，離子(zi)擴散(san)速度快，離子(zi)交(jiao)(jiao)換(huan)速度也快很多(duo)，約比凝膠型(xing)(xing)樹(shu)脂快約十倍。使用時的(de)(de)作用快、，所需處理時間縮(suo)短。大(da)孔(kong)樹(shu)脂還有多(duo)種(zhong)優(you)點：耐溶(rong)脹，不易(yi)碎裂(lie)，耐氧(yang)化，耐磨損，耐熱及(ji)耐溫度變化，以及(ji)對有機大(da)分(fen)子(zi)物質(zhi)較(jiao)易(yi)吸(xi)附和交(jiao)(jiao)換(huan)，因而抗污(wu)染力強，并(bing)較(jiao)容易(yi)再(zai)生。
