Ukumiselwa kwe-chlorine eshiyekileyo/i-chlorine iyonke nge-DPD spectrophotometry

I-Chlorine disinfectant yi-disinfectant esetyenziswa ngokuqhelekileyo kwaye isetyenziswa ngokubanzi kwinkqubo yokutshatyalaliswa kwentsholongwane yamanzi epompo, amachibi okudada, i-tableware, njl. chlorination disinfection iye yatsala ingqalelo eyandisiweyo. Umxholo oshiyekileyo weklorini luphawu olubalulekileyo lokuvavanya ukusebenza kokubulawa kweentsholongwane emanzini.

Ukuze kuthintelwe ukuphinda kubekho iibhaktheriya ezishiyekileyo, iintsholongwane kunye nezinye iintsholongwane emanzini, emva kokuba amanzi ehlanjululwe ngeentsholongwane ezineklorini kangangexesha elithile, kufuneka kubekho isixa esifanelekileyo se-chlorine eseleyo emanzini ukuqinisekisa ukuqhubeka. ukuvala inzala. Nangona kunjalo, xa umxholo we-chlorine oseleyo uphezulu kakhulu, unokwenza lula ukungcoliseka kwesibini komgangatho wamanzi, ngokuqhelekileyo kukhokelela ekuveliseni i-carcinogens, kubangele i-anemia ye-hemolytic, njl., enemiphumo ethile eyingozi kwimpilo yabantu. Ke ngoko, ukulawula ngempumelelo kunye nokufumanisa umxholo oshiyekileyo weklorini kubalulekile kunyango lonikezelo lwamanzi.

Kukho iintlobo ezininzi zeklorini emanzini:

I-chlorine eshiyekileyo (i-chlorine yamahhala): Iklorini ekwimo ye-hypochlorous acid, i-hypochlorite, okanye i-chlorine edibeneyo edibeneyo.
I-chlorine edibeneyo: I-chlorine ngendlela ye-chloramines kunye ne-organochloramines.
I-chlorine iyonke: Iklorini ekhoyo ikwimo ye-chlorine eshiyekileyo yasimahla okanye i-chlorine edityanisiweyo okanye zombini.

Ukumisela i-chlorine eseleyo kunye ne-chlorine epheleleyo emanzini, indlela ye-o-toluidine kunye nendlela ye-iodine yayisetyenziswa ngokubanzi kwixesha elidlulileyo. Ezi ndlela zinzima ukusebenza kwaye zinemijikelo yokuhlalutya emide (efuna amagcisa aqeqeshiweyo), kwaye ayinakuhlangabezana neemfuno zovavanyo olukhawulezayo noluyimfuneko lomgangatho wamanzi. iimfuno kwaye azilulungele uhlalutyo lwendawo; ngaphezu koko, ngenxa yokuba i-o-toluidine reagent i-carcinogenic, indlela yokufumanisa i-chlorine eshiyekileyo "kwiMigangatho yococeko lwamanzi okusela" eyabhengezwa nguMphathiswa wezeMpilo weRiphabhliki yaBantu baseChina ngoJuni 2001 isuse i-o-toluidine reagent. Indlela ye-benzidine yatshintshwa yi-DPD spectrophotometry.

Indlela ye-DPD okwangoku yenye yezona ndlela zichanekileyo zokubona kwangoko intsalela yeklorini. Xa kuthelekiswa nendlela ye-OTO yokufumanisa i-chlorine eshiyekileyo, ukuchaneka kwayo kuphezulu.
Ubhaqo lwe-DPD yolwahlulo lwefotometric Ifotoometry yindlela yokuhlalutya yekhemistri edla ngokusetyenziswa ukulinganisa ukuxinana kwentsalela yeklorini yoxinaniso oluphantsi okanye iyonke iklorine kwiisampulu zamanzi. Le ndlela imisela ukugxilwa kweklorini ngokulinganisa umbala oveliswa yikhemikhali ethile.
Imigaqo esisiseko ye-DPD photometry yile ilandelayo:
1. Ukusabela: Kwiisampulu zamanzi, i-chlorine eshiyekileyo okanye i-chlorine iyonke iphendula kunye ne-reagents ethile yeekhemikhali (i-DPD reagents). Le mpendulo ibangela ukuba umbala wesisombululo utshintshe.
2. Ukutshintsha kombala: Ikhompawundi eyenziwe yi-reagent ye-DPD kunye ne-chlorine iya kutshintsha umbala wesisombululo sesampulu samanzi ukusuka kumbala ongenambala okanye ophuzi obomvu ukuya obomvu okanye omfusa. Olu tshintsho lombala lungaphakathi koluhlu olubonakalayo.
3. Umlinganiselo we-Photometric: Sebenzisa i-spectrophotometer okanye i-photometer ukulinganisa ukuxhamla okanye ukuhanjiswa kwesisombululo. Lo mlinganiselo uqhele ukwenziwa kumda wamaza obuthile (udla ngokuba yi-520nm okanye obunye ubude obukhethekileyo).
4. Uhlalutyo kunye nokubala: Ngokusekelwe kwixabiso elilinganisiweyo lokutsalwa okanye ukugqithiswa kwexabiso, sebenzisa i-curve eqhelekileyo okanye ifomula yoxinaniso ukugqiba ukuxinwa kweklorini kwisampuli yamanzi.
I-photometry ye-DPD idla ngokusetyenziswa ngokubanzi kwintsimi yonyango lwamanzi, ngakumbi ekuvavanyeni amanzi okusela, umgangatho wamanzi edama lokuqubha kunye neenkqubo zokucocwa kwamanzi kwimizi-mveliso. Yindlela elula kwaye echanekileyo enokulinganisa ngokukhawuleza ukuxinwa kweklorini ukuqinisekisa ukuba i-chlorine yoxinaniso emanzini iphakathi koluhlu olufanelekileyo lokuphelisa ibhaktheriya kunye nezinye ii-microorganisms eziyingozi.
Nceda uqaphele ukuba iindlela ezithile zokuhlalutya kunye nezixhobo zinokwahluka phakathi kwabavelisi kunye neebhubhoratri, ngoko ke xa usebenzisa i-photometry ye-DPD, nceda ubhekisele kwindlela ethile yokuhlalutya kunye nesixhobo sokusebenzisa isixhobo sokuqinisekisa ukuchaneka nokuphindaphinda.
I-LH-P3CLO okwangoku ibonelelwa yi-Lianhua yimitha ye-chlorine eshiyekileyo ephathekayo ehambelana ne-DPD photometric method.
