水處理中微電解法(fa)中的原電池反(fan)應

微(wei)電(dian)(dian)解法處理工業廢水是(shi)(shi)(shi)基于電(dian)(dian)化學中(zhong)(zhong)的(de)(de)原(yuan)(yuan)電(dian)(dian)池(chi)(chi)(chi)反(fan)(fan)應(ying)，將金屬(shu)陽(yang)極(ji)(ji)直接和(he)陰極(ji)(ji)材料接觸(chu)在一(yi)起并浸沒在電(dian)(dian)解質(zhi)溶液(ye)中(zhong)(zhong)則發生(sheng)(sheng)原(yuan)(yuan)電(dian)(dian)池(chi)(chi)(chi)反(fan)(fan)應(ying)而(er)形(xing)(xing)成(cheng)(cheng)腐(fu)(fu)(fu)蝕(shi)電(dian)(dian)池(chi)(chi)(chi)，就發生(sheng)(sheng)所(suo)謂的(de)(de)腐(fu)(fu)(fu)蝕(shi)反(fan)(fan)應(ying)，金屬(shu)陽(yang)極(ji)(ji)被(bei)(bei)腐(fu)(fu)(fu)蝕(shi)而(er)消耗(hao)。腐(fu)(fu)(fu)蝕(shi)電(dian)(dian)池(chi)(chi)(chi)又(you)可分(fen)(fen)為(wei)(wei)微(wei)觀(guan)腐(fu)(fu)(fu)蝕(shi)電(dian)(dian)池(chi)(chi)(chi)和(he)宏觀(guan)腐(fu)(fu)(fu)蝕(shi)電(dian)(dian)池(chi)(chi)(chi)，前(qian)者是(shi)(shi)(shi)指(zhi)在金屬(shu)表面(mian)由于存(cun)在許多極(ji)(ji)微(wei)小(xiao)的(de)(de)電(dian)(dian)極(ji)(ji)而(er)形(xing)(xing)成(cheng)(cheng)的(de)(de)電(dian)(dian)池(chi)(chi)(chi)，后者是(shi)(shi)(shi)指(zhi)由肉眼(yan)可見到的(de)(de)電(dian)(dian)極(ji)(ji)所(suo)構成(cheng)(cheng)的(de)(de)“大電(dian)(dian)池(chi)(chi)(chi)”。鑄鐵(tie)(tie)(tie)(tie)是(shi)(shi)(shi)鐵(tie)(tie)(tie)(tie)和(he)碳的(de)(de)合金，即由純鐵(tie)(tie)(tie)(tie)和(he) Fe3C 及一(yi)些雜質(zhi)組(zu)成(cheng)(cheng)，如炭、硅(gui)、錳等(deng)成(cheng)(cheng)分(fen)(fen)，并且鑄鐵(tie)(tie)(tie)(tie)是(shi)(shi)(shi)一(yi)種多孔性物質(zhi)，具有(you)較高的(de)(de)表面(mian)活性。Fe3C和(he)其他雜質(zhi)顆粒以極(ji)(ji)小(xiao)的(de)(de)顆粒形(xing)(xing)式分(fen)(fen)散在鑄鐵(tie)(tie)(tie)(tie)內(nei)，由于它們的(de)(de)電(dian)(dian)極(ji)(ji)電(dian)(dian)勢比鐵(tie)(tie)(tie)(tie)的(de)(de)低，當浸入電(dian)(dian)解質(zhi)溶液(ye)中(zhong)(zhong)時就形(xing)(xing)成(cheng)(cheng)了成(cheng)(cheng)千上萬個細小(xiao)的(de)(de)微(wei)電(dian)(dian)池(chi)(chi)(chi)，在它的(de)(de)表面(mian)就有(you)電(dian)(dian)流(liu)(liu)在無數個細小(xiao)的(de)(de)電(dian)(dian)池(chi)(chi)(chi)內(nei)流(liu)(liu)動，鐵(tie)(tie)(tie)(tie)作為(wei)(wei)陽(yang)極(ji)(ji)被(bei)(bei)腐(fu)(fu)(fu)蝕(shi)消耗(hao)，碳化鐵(tie)(tie)(tie)(tie)及雜質(zhi)則成(cheng)(cheng)為(wei)(wei)陰極(ji)(ji)，發生(sheng)(sheng)電(dian)(dian)極(ji)(ji)反(fan)(fan)應(ying)。當體系中(zhong)(zhong)

有(you)惰(duo)性(xing)碳(tan)(如石墨、焦炭、活性(xing)炭、煤等(deng))等(deng)宏觀陰極材料存在(zai)時(shi)，又可以組成(cheng)宏觀電池。
