　　一(yi)、電解設備中電解條(tiao)件的(de)抉擇
    電解(jie)目的是要(yao)去除(chu)鍍液(ye)中(zhong)的雜質(zhi)，然而在(zai)電解(jie)去除(chu)雜質(zhi)的同時，往(wang)往(wang)也有溶液(ye)中(zhong)金屬(shu)離子的放電堆積(ji)(ji)。為(wei)了(le)達到去除(chu)雜質(zhi)的速率，減慢溶液(ye)中(zhong)有些金屬(shu)離子的堆積(ji)(ji)速率，就要(yao)注(zhu)意電解(jie)解(jie)決的操(cao)作條件。

　　1、溫(wen)(wen)(wen)度和pH值：電解(jie)(jie)時(shi)溫(wen)(wen)(wen)度和pH的(de)(de)(de)抉擇，準則上(shang)也(ye)是(shi)要依據電鍍(du)時(shi)雜(za)(za)質(zhi)(zhi)(zhi)起不良影響(xiang)較大的(de)(de)(de)溫(wen)(wen)(wen)度和pH范(fan)疇。例如鍍(du)鎳(nie)溶液(ye)(ye)(ye)中(zhong)的(de)(de)(de)銅雜(za)(za)質(zhi)(zhi)(zhi)和NO3-雜(za)(za)質(zhi)(zhi)(zhi)，在(zai)(zai)(zai)pH較低(di)(di)時(shi)的(de)(de)(de)影響(xiang)較大，所以電解(jie)(jie)去除鍍(du)鎳(nie)溶液(ye)(ye)(ye)中(zhong)的(de)(de)(de)銅雜(za)(za)質(zhi)(zhi)(zhi)和NO3-雜(za)(za)質(zhi)(zhi)(zhi)時(shi)，應選(xuan)用低(di)(di)pH停止電解(jie)(jie)，在(zai)(zai)(zai)這(zhe)(zhe)樣的(de)(de)(de)條件下，去除雜(za)(za)質(zhi)(zhi)(zhi)的(de)(de)(de)速(su)率較快。有些(xie)雜(za)(za)質(zhi)(zhi)(zhi)在(zai)(zai)(zai)電解(jie)(jie)進程中(zhong)會合成為氣體(ti)(如NO3-在(zai)(zai)(zai)陰極(ji)上(shang)復原(yuan)為氮(dan)氧化物或氨(an)，Cl-在(zai)(zai)(zai)陽極(ji)上(shang)氧化為Cl2，等，這(zhe)(zhe)時(shi)就應選(xuan)用低(di)(di)溫(wen)(wen)(wen)電解(jie)(jie)，使電解(jie)(jie)進程中(zhong)造(zao)成的(de)(de)(de)氣體(ti)揮發逸出(氣體(ti)在(zai)(zai)(zai)溶液(ye)(ye)(ye)中(zhong)的(de)(de)(de)溶解(jie)(jie)度，個別(bie)隨(sui)溫(wen)(wen)(wen)度降低(di)(di)而升高(gao))，從而避免它溶解(jie)(jie)于水(shui)而從新沾污鍍(du)液(ye)(ye)(ye)。

    依(yi)照(zhao)個別規律，隨著鍍液(ye)溫度(du)的(de)降低，電解(jie)去除雜質的(de)速率(lv)也增大(da)，所(suo)以當(dang)加溫對鍍液(ye)其中成分沒有影響時，電解(jie)宜在(zai)加溫下停止(zhi)。但到底(di)在(zai)什么溫度(du)為(wei)好，可以通過小實驗確定(ding)

　　2、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)：電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)時(shi)，多(duo)大(da)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)會更好(hao)，準則(ze)上要依(yi)照(zhao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)鍍時(shi)雜質(zhi)(zhi)起不(bu)良影(ying)(ying)(ying)(ying)響(xiang)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)范(fan)疇(chou)。也就(jiu)是說，在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)鍍進程(cheng)中，若雜質(zhi)(zhi)的影(ying)(ying)(ying)(ying)響(xiang)反(fan)(fan)映在(zai)低(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)區(qu)，那么電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)時(shi)應管制在(zai)低(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)下(xia)(xia)進行，倘若雜質(zhi)(zhi)的影(ying)(ying)(ying)(ying)響(xiang)反(fan)(fan)映在(zai)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)區(qu)，則(ze)應選用(yong)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)；假如雜質(zhi)(zhi)在(zai)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)區(qu)和低(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)區(qu)都(dou)有(you)影(ying)(ying)(ying)(ying)響(xiang)，那么可先用(yong)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)一(yi)段工夫，而(er)后再改用(yong)低(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)，直至(zhi)鍍液恢復正常(chang)。在(zai)個(ge)別狀況(kuang)下(xia)(xia)，但(dan)凡(fan)用(yong)低(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)可以(yi)去除的雜質(zhi)(zhi)，為了增加鍍液中一(yi)些放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)金屬離子(zi)的堆積，個(ge)別都(dou)采用(yong)低(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)。現實上，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)鍍時(shi)，大(da)多(duo)數雜質(zhi)(zhi)的影(ying)(ying)(ying)(ying)響(xiang)反(fan)(fan)映在(zai)低(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)區(qu)，所以(yi)通常(chang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)密(mi)(mi)(mi)度(du)(du)管制在(zai)0.1A／dm2～0.5A／dm2之間。

　　3、攪(jiao)拌：電(dian)(dian)解既然(ran)是依靠雜(za)質(zhi)在陰極(或(huo)陽極)的(de)外(wai)表上反饋而被(bei)除(chu)去，那么就應(ying)(ying)供應(ying)(ying)條(tiao)件(jian)，使雜(za)質(zhi)與(yu)電(dian)(dian)極外(wai)表有充沛的(de)接觸時機。攪(jiao)拌可以加快雜(za)質(zhi)運(yun)轉，使它(ta)與(yu)電(dian)(dian)極的(de)接觸時機增(zeng)多(duo)，提高處理效果，電(dian)(dian)解時應(ying)(ying)攪(jiao)拌鍍液。 

　二(er)、電(dian)(dian)鍍電(dian)(dian)解的(de)要求(qiu)

    1、首先(xian)要查明雜(za)(za)質(zhi)(zhi)能否起源于(yu)電解過程：電解可以去(qu)除某些雜(za)(za)質(zhi)(zhi)，但有(you)時也會(hui)發生(sheng)雜(za)(za)質(zhi)(zhi)。例如(ru)有(you)害(hai)雜(za)(za)質(zhi)(zhi)起源于(yu)不(bu)純的陽極(ji)，電解時仍用這種陽極(ji)，那(nei)么隨著電解進行時，雜(za)(za)質(zhi)(zhi)會(hui)越積越多；又如(ru)雜(za)(za)質(zhi)(zhi)起源于(yu)某些化合物在電極(ji)上的分解，那(nei)么電解將(jiang)使這類分解產物逐(zhu)步增多。這樣的電解，不(bu)能凈化鍍(du)液，反(fan)而(er)會(hui)不(bu)時加重鍍(du)液的污染。因而(er)，在電解處(chu)理前(qian)，要先(xian)的查看，預防(fang)處(chu)理中產生(sheng)有(you)害(hai)雜(za)(za)質(zhi)(zhi)。

    2、 電(dian)解用(yong)(yong)的(de)陰極(ji)(假陰極(ji))面積(ji)(ji)要盡能夠大：用(yong)(yong)電(dian)解法去(qu)(qu)除(chu)雜(za)(za)質(zhi)，大多是(shi)在陰極(ji)外(wai)表(biao)上進行的(de)，所以增大陰極(ji)面積(ji)(ji)，可以進步(bu)去(qu)(qu)除(chu)雜(za)(za)質(zhi)的(de)效率,同(tong)(tong)時為了在不同(tong)(tong)的(de)電(dian)流(liu)密度部(bu)(bu)位電(dian)解去(qu)(qu)除(chu)鍍液中不同(tong)(tong)雜(za)(za)質(zhi)或(huo)同(tong)(tong)一種雜(za)(za)質(zhi)，要求電(dian)解用(yong)(yong)的(de)陰極(ji)做(zuo)成凹凸(tu)的(de)外(wai)表(biao)，這(zhe)樣可以進步(bu)電(dian)解的(de)效果。但陰極(ji)上的(de)凹處不宜太深，以避(bi)免電(dian)流(liu)密渡過小而使(shi)雜(za)(za)質(zhi)不能在這(zhe)些部(bu)(bu)位堆積(ji)(ji)或(huo)復(fu)原。

    3、電(dian)(dian)解進程中，要定時(shi)刷洗陰(yin)(yin)極(ji)：因為電(dian)(dian)解的時(shi)間一(yi)般都比擬長，長時(shi)間的電(dian)(dian)解進程中，陰(yin)(yin)極(ji)上能夠(gou)會發生(sheng)蓬(peng)松的堆積物，它的零落會從新沾污鍍液，所以在(zai)電(dian)(dian)解一(yi)段工夫后，應將陰(yin)(yin)極(ji)取出刷洗，把陰(yin)(yin)極(ji)上蓬(peng)松或(huo)不良的堆積物刷去(qu)后再持續電(dian)(dian)解。

    4、電解(jie)解(jie)決前，先做(zuo)小(xiao)實驗預(yu)計一(yi)下電解(jie)的效(xiao)果和時間(jian)：有些(xie)雜質(zhi)，用電解(jie)很難除去，若(ruo)一(yi)味(wei)地采用電解(jie)處理，可能花了很長工夫也(ye)不能使鍍(du)液恢復正常。
