Chlorine disinfectant ke sebolaya dikokwana-hloko se sebediswang ka tlwaelo mme se sebediswa haholo tshebetsong ya ho bolaya dikokwana-hloko tsa metsi a pompo, matamo a ho sesa, tableware, jj. Leha ho le jwalo, dibolaya-mafu tse nang le chlorine di tla hlahisa mefuta e fapaneng ya dihlahiswa nakong ya disinfection, kahoo polokeho ya boleng ba metsi kamora chlorination disinfection e hohetse tlhokomelo e ntseng e eketseha. Masala a chlorine ke sesupo sa bohlokoa sa ho lekola katleho ea ho bolaea likokoana-hloko ka metsing.
E le ho thibela ho ata ha libaktheria tse setseng, livaerase le likokoana-hloko tse ling ka metsing, ka mor'a hore metsi a hloekisoe ka likokoana-hloko tse nang le chlorine ka nako e itseng, ho lokela ho ba le palo e lekaneng ea masala a chlorine metsing ho netefatsa hore ho tsoela pele. bokhoni ba ho phunya. Leha ho le joalo, ha karolo e setseng ea chlorine e phahame haholo, e ka baka habonolo tšilafalo ea bobeli ea boleng ba metsi, hangata e lebisa tlhahisong ea li-carcinogens, e bakang khaello ea mali ea hemolytic, joalo-joalo, e nang le liphello tse itseng tse kotsi bophelong ba motho. Ka hona, ho laola le ho lemoha ka nepo masala a chlorine ho bohlokoa kalafong ea phepelo ea metsi.
Ho na le mefuta e 'maloa ea chlorine metsing:
Residual chlorine (klorine e sa lefelloeng): Chlorine ka sebōpeho sa hypochlorous acid, hypochlorite, kapa dissolved elemental chlorine.
Chlorine e kopantsoeng: Chlorine ka sebopeho sa chloramine le organochloramines.
Kakaretso ea chlorine: Chlorine e teng ka sebopeho sa masala a mahala kapa chlorine e kopaneng kapa ka bobeli.
Bakeng sa boikemisetso ba chlorine e setseng le chlorine e feletseng ka metsing, mokhoa oa o-toluidine le mokhoa oa iodine o ne o sebelisoa haholo nakong e fetileng. Mekhoa ena e boima ho sebetsa le ho ba le linako tse telele tsa tlhahlobo (e hlokang litsebi tsa litsebi), 'me ha e khone ho fihlela litlhoko tsa tlhahlobo e potlakileng le e hlokahalang ea boleng ba metsi. litlhoko 'me ha lia lokela ho hlahlojoa setšeng; ho feta moo, kaha reagent ea o-toluidine e na le kankere, mokhoa o setseng oa ho lemoha chlorine ho "Maemo a Bohloeki bakeng sa Metsi a Nooang" o phatlalalitsoeng ke Lekala la Bophelo la People's Republic of China ka June 2001 o tlositse reagent ea o-toluidine. Mokhoa oa benzidine o ile oa nkeloa sebaka ke DPD spectrophotometry.
Mokhoa oa DPD hajoale ke o mong oa mekhoa e nepahetseng ka ho fetesisa ea ho lemoha hang-hang masala a chlorine. Ha ho bapisoa le mokhoa oa OTO oa ho lemoha masala a chlorine, ho nepahala ha eona ho holimo.
DPD e khethollang photometric Mokhoa ona o etsa qeto ea hore na chlorine ke eng ka ho lekanya 'mala o hlahisoang ke lik'hemik'hale tse itseng.
Melao-motheo ea DPD photometry ke e latelang:
1. Karabelo: Mesampong ea metsi, masala a chlorine kapa chlorine kaofela e kopana le li-reagents tsa lik'hemik'hale tse itseng (li-reagents tsa DPD). Karabelo ena e etsa hore 'mala oa tharollo o fetohe.
2. Phetoho ea 'mala: Motsoako o entsoeng ke DPD reagent le chlorine o tla fetola' mala oa tharollo ea metsi ho tloha ho se nang 'mala kapa mosehla o khanyang ho ea ho o mofubelu kapa o pherese. Phetoho ena ea 'mala e ka har'a mefuta e bonahalang ea spectrum.
3. Tekanyo ea photometric: Sebelisa spectrophotometer kapa photometer ho lekanya ho monya kapa ho fetisoa ha tharollo. Tekanyo ena hangata e etsoa ka bolelele bo itseng ba maqhubu (hangata 520nm kapa bolelele bo bong bo itseng).
4. Tlhahlobo le lipalo: Ho ipapisitsoe le boleng bo lekantsoeng ba ho monya kapa phetiso, sebelisa lekhalo le tloaelehileng kapa foromo ea mahloriso ho fumana hore na chlorine e kae sampoleng ea metsi.
DPD photometry e atisa ho sebelisoa haholo tšimong ea phekolo ea metsi, haholo-holo ho hlahloba metsi a nooang, boleng ba metsi a letamo la ho sesa le mekhoa ea ho hloekisa metsi a indasteri. Ke mokhoa o batlang o le bonolo le o nepahetseng o ka lekanyang ka potlako motsoako oa chlorine ho netefatsa hore motsoako oa chlorine metsing o ka har'a sebaka se loketseng ho felisa libaktheria le likokoana-hloko tse ling tse kotsi.
Ka kopo hlokomela hore mekhoa le lisebelisoa tse khethehileng tsa tlhahlobo li ka 'na tsa fapana pakeng tsa bahlahisi le lilaboratori, kahoo ha u sebelisa photometry ea DPD, ka kopo sheba mokhoa o khethehileng oa ho hlahloba le buka ea ts'ebetso ea lisebelisoa ho netefatsa ho nepahala le ho pheta-pheta.
