舊電極響應(yīng)遲緩，膜電阻高，斜率低。用氫氟酸浸蝕掉外層膠層，經(jīng)常能改善電極性能。若能用此法定期***內(nèi)外層膠層，則電極的壽命幾乎是無限的。4、參比電極的貯存銀-氯化銀電極比較好的貯存液是飽和氯化鉀溶液，高濃度氯化鉀溶液可以防止氯化銀在液接界處沉淀，并維持液接界處于工作狀態(tài)。此方法也適用于復(fù)合電極的貯存，內(nèi)蒙古原裝PH計(jì)。5、參比電極的再生參比電極發(fā)生的問題絕大多數(shù)是由液接界堵塞引起的，可用下列方法解決：（1）浸泡液接界：用10%飽和氯化鉀溶液和90%蒸餾水的混合液，加熱至60～70℃，將電極浸入約5cm，浸泡20分鐘至1小時(shí)。此法可溶去電極端部的結(jié)晶。（2）氨浸泡：當(dāng)液接界被氯化銀堵塞時(shí)可用濃氨水浸除。具體方法是將電極內(nèi)充洗凈，液放空后浸入氨水中10～20分鐘，但不要讓氨水進(jìn)入電極內(nèi)部。取出電極用蒸餾水洗凈，重新加入內(nèi)充液后繼續(xù)使用。（3）真空方法：將軟管套住參比電極液接界，使用水流吸氣泵，抽吸部分內(nèi)充液穿過液接界，內(nèi)蒙古原裝PH計(jì)，除去機(jī)械堵塞物。（4）煮沸液接界：銀-氯化銀參比電極的液接界浸入沸水中10～20秒。注意，下一次煮沸前，應(yīng)將電極冷卻到室溫，內(nèi)蒙古原裝PH計(jì)。（5）當(dāng)以上方法均無效時(shí)，可采用砂紙研磨的機(jī)械方法去除堵塞。此法可能會(huì)使研磨下的砂粒塞入液接界。pH計(jì)，是指用來測(cè)定溶液酸堿度值的儀器。內(nèi)蒙古原裝PH計(jì)</p><div
