I-DRK-T453 Isinxibo esiKhuselekileyo esichasene ne-Acid kunye ne-alkali yoVavanyo lweSistim yeSikhokelo sokuSebenza—Isivavanyi sexesha lokungena

Umgaqo wokusebenza

Indlela ye-conductivity kunye nesixhobo sexesha esizenzekelayo sisetyenziselwa ukuvavanya ixesha lokungena kwempahla yokukhusela ilaphu ye-asidi kunye neekhemikhali ze-alkali.Isampuli ifakwe phakathi kwamaphepha e-electrode aphezulu nangaphantsi, kwaye ucingo oluqhubayo luxhunywe kwiphepha eliphezulu le-electrode kwaye lidibanisa nomgangatho ophezulu wesampuli.Xa kwenzeka into yokungena, isiphaluka sivuliwe kwaye ixesha liyayeka.

Ubume besixhobo

Ulwakhiwo lwesixhobo lubandakanya ikakhulu la malungu alandelayo:

1. Iphepha le-electrode ephezulu 2. Iphepha le-electrode elisezantsi 3. Ibhokisi yokuvavanya 4. Iphaneli yokulawula

Iiparamitha zobuGcisa

1. Uluhlu lwexesha lovavanyo: 0～99.99min

2. Inkcazo yomfanekiso: 100mm×100mm

3. Ukunikezelwa kwamandla: AC220V 50Hz

4. Indawo yovavanyo: ubushushu (17～30)℃, ukufuma okuhambelanayo: (65±5)%

5. Ama-Reagents: Isithembiso seempahla ezikhuselayo ze-asidi kufuneka zihlolwe nge-80% ye-sulfuric acid, i-30% ye-hydrochloric acid, i-40% ye-nitric acid;Impahla ekhuselayo ye-alkali ye-inorganic kufuneka ihlolwe nge-30% ye-sodium hydroxide;Impahla yokukhusela i-electrodeless acid kufuneka ibe yi-80% ye-Sulfuric acid, i-30% ye-hydrochloric acid, i-40% ye-nitric acid, kunye ne-30% ye-sodium hydroxide yavavanywa.

Imigangatho esebenzayo:

GB24540-2009 Isinxibo esikhuselayo Iasidi-isiseko sekhemikhali isinxibo esikhuselayo kwiSihlomelo A

Lungisa isampuli

1. Isampula: Kwisisombululo ngasinye sovavanyo, thatha iisampulu ezi-6 kwimpahla yokukhusela, inkcazo yi-100mm × 100m,

Phakathi kwabo, i-3 iisampulu ezingenamthungo kunye ne-3 iisampulu ezidibeneyo.Umthungo womfanekiso othungelweyo kufuneka ube sembindini wesampulu.

2. Ukuhlamba isampuli: jonga i-GB24540-2009 iSihlomelo K ngeendlela ezithile zokuhlamba kunye namanyathelo

Einkqubo xperiment

1. Qhagamshela unikezelo lwamandla lwesixhobo kunye nentambo yamandla enikezelweyo kwaye uvule iswitshi yamandla.

2. Ukusasaza isampuli esilungisiweyo esicwangcisiweyo phakathi kweepleyiti ze-electrode eziphezulu kunye nezantsi, uphonsa i-0.1 mL ye-reagent ukusuka kumngxuma ojikelezayo kunye nocingo lokuqhuba ukuya kumphezulu wesampuli, kwaye ucinezele iqhosha elithi "Qala / Yeka" ngexesha elifanayo ukuqalisa. ixesha.Kwimizekelo ene-seams, i-wire conductive ifakwe kwi-seams kwaye i-reagents ihlahlela kwii-seams.

3. Emva kokwenzeka kokungena, isixhobo siyayeka ukubala ixesha ngokuzenzekelayo, isibane sesalathisi sivuliwe, kwaye i-alam iyakhala.Ngeli xesha, ixesha lokuyeka lirekhodwa.

4. Ukwahlula i-electrodes ephezulu nangaphantsi kwaye ucinezele iqhosha elithi "reset" ukubuyisela imeko yokuqala yesixhobo.Emva kovavanyo olunye, coca intsalela kwi-electrode kunye nocingo oluqhubayo.

5. Ukuba kukho nayiphi na imeko engalindelekanga ngexesha lovavanyo, unokucofa ngokuthe ngqo iqhosha elithi "Qala / Yeka" ukuyeka ixesha kwaye unike i-alamu.

6. Phinda amanyathelo 2 ukuya ku-4 de zonke iimvavanyo zenziwe.Emva kokuba uvavanyo lugqityiwe, cima amandla esixhobo.

7. Iziphumo zokubala:

Kwiisampulu ezingenamthungo: ufundo luphawulwe njenge-t1, t2, t3;ixesha lokungena

Kwiisampuli ezinemithungo: ufundo lurekhodwa njenge-t4, t5, t6;ixesha lokungena

Ukulumkela

1. Isisombululo sovavanyo esisetyenziswe kuvavanyo siyingozi kakhulu.Nceda uqaphele ukhuseleko kwaye uthathe amanyathelo okukhusela ngexesha lovavanyo.

2. Sebenzisa i-dropper kwi-pipette isisombululo sovavanyo ngexesha lovavanyo.

3. Emva kovavanyo, hlambulula umphezulu webhentshi yokuvavanya kunye nesixhobo ngexesha lokuthintela ukubola.

4. Isixhobo kufuneka sisekelwe ngokuthembekileyo.
