CPS11D-7AS21恩德斯豪斯電極分類：

任何(he)金屬與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解液接觸都會產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)（位），這是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極的(de)主要的(de)特征性(xing)質如(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極界面上存在(zai)(zai)著單*種(zhong)氧化(hua)還(huan)原對(dui)的(de)快(kuai)速電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子交換，即存在(zai)(zai)著交換電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流很大的(de)（見遷越超電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)）單一電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極反應，這種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極能很快(kuai)建立電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)化(hua)學平(ping)衡，稱為(wei)可(ke)逆(ni)(ni)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極。可(ke)逆(ni)(ni)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)能較(jiao)(jiao)長時期維持(chi)穩定，抗干擾能力較(jiao)(jiao)大，并能正確(que)測量。它是可(ke)逆(ni)(ni)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)必要組成部分(fen)，是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)位分(fen)析法測量裝置的(de)核心部件(jian)，有(you)重(zhong)要的(de)實用意(yi)義。可(ke)逆(ni)(ni)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極有(you)以(yi)下(xia)類型：

① 金(jin)屬電(dian)(dian)極，如銅電(dian)(dian)極（圖(tu)2），其特(te)點是氧化還原對可以遷越相(xiang)界面。

② 氧化(hua)還(huan)原(yuan)電極(ji)，例如Pt|Fe，Fe電極(ji) （圖3）、Pt|Mn,MnO嬄(嬄)，H電極(ji)等。它的(de)氧化(hua)還(huan)原(yuan)對不能遷(qian)越電極(ji)相界面，電極(ji)的(de)鉑Pt只表(biao)示電極(ji)金屬(shu)是惰性的(de)，它只是提供電子交換的(de)場所(suo)，實(shi)際應用時(shi)可采用任何(he)惰性金屬(shu)。

③ 氣體電極(ji)，是氧化還原(yuan)對的(de)一個(ge)組分為(wei)氣體時的(de)氧化還原(yuan)電極(ji) （圖 4），例如氫電極(ji) (Pt|H2|H）、氯電極(ji)（Pt|Cl2|Cl）等。為(wei)了加速達成(cheng)平衡，金屬鉑(bo)上(shang)需(xu)要鍍上(shang)鉑(bo)黑(hei)以增加表面積并起電催化作用。

電極

④ 難溶鹽(yan)(yan)電(dian)(dian)(dian)極，氧化還原對的(de)(de)一個(ge)(ge)(ge)組分是(shi)難溶鹽(yan)(yan)或其他(ta)固相。因此它(ta)包含(han)三個(ge)(ge)(ge)物相、 兩個(ge)(ge)(ge)界面（圖1），在每一相界面上存(cun)在著(zhu)單一的(de)(de)快速遷(qian)越過程(cheng)，如甘(gan)汞(gong)(gong)電(dian)(dian)(dian)極（Hg|Hg2Cl2|Cl）、電(dian)(dian)(dian)極（Hg|HgO|OH）。在甘(gan)汞(gong)(gong)電(dian)(dian)(dian)極中，甘(gan)汞(gong)(gong)與電(dian)(dian)(dian)解(jie)液的(de)(de)溶解(jie)平衡*受電(dian)(dian)(dian)液中濃度較(jiao)高的(de)(de)Cl所(suo)控制，Cl在Hg2Cl2|電(dian)(dian)(dian)液界面上的(de)(de)交換速率也很快，故它(ta)的(de)(de)電(dian)(dian)(dian)極電(dian)(dian)(dian)勢(shi)非常(chang)穩定(ding)。它(ta)是(shi)常(chang)見(jian)的(de)(de)參比電(dian)(dian)(dian)極，有些書刊稱(cheng)這類電(dian)(dian)(dian)極為第二類電(dian)(dian)(dian)極。

膜(mo)(mo)電(dian)(dian)極(ji) 利用隔膜(mo)(mo)對(dui)于(yu)單種離(li)(li)子(zi)的(de)(de)(de)透過性或(huo)膜(mo)(mo)表面(mian)與電(dian)(dian)解液的(de)(de)(de)離(li)(li)子(zi)交換平(ping)衡所建立的(de)(de)(de)電(dian)(dian)勢來測量(liang)電(dian)(dian)液中特定離(li)(li)子(zi)活度(du)的(de)(de)(de)裝置（圖(tu)5），例如玻璃電(dian)(dian)極(ji)、離(li)(li)子(zi)選擇(ze)性電(dian)(dian)極(ji)。

化學(xue)修飾電極 利(li)用吸附(fu)、涂敷、聚合、化學(xue)反(fan)應等(deng)方法把活性基團、催化物質(zhi)等(deng)附(fu)著(zhu)在電極金屬（包括石墨(mo)、半(ban)導體）表面上，使之具有較強的(de)特征功(gong)能。這是70年代以來電極制備方法的(de)新發展。
