Chlorine disinfectant ndi mankhwala omwe amagwiritsidwa ntchito kwambiri ndipo amagwiritsidwa ntchito kwambiri popha tizilombo toyambitsa matenda a madzi apampopi, malo osambira, tableware, ndi zina zotero. chlorination disinfection yakopa chidwi. Zotsalira za klorini ndi chizindikiro chofunikira powunika mphamvu ya mankhwala ophera tizilombo m'madzi.
Pofuna kuletsa kuchulukirachulukira kwa mabakiteriya otsalira, ma virus ndi tizilombo tating'onoting'ono tamadzi m'madzi, madziwo atayidwa ndi mankhwala okhala ndi chlorine kwa nthawi yayitali, payenera kukhala kuchuluka koyenera kwa chlorine yotsalira m'madzi kuti zitsimikizidwe kuti zikupitilira. kuthekera kotsekereza. Komabe, zotsalira za klorini zikachuluka kwambiri, zimatha kuyambitsa kuipitsidwa kwachiwiri kwamadzi abwino, nthawi zambiri kumayambitsa kupanga ma carcinogens, kumayambitsa hemolytic anemia, ndi zina zotere, zomwe zimakhala ndi zotsatirapo zoyipa pamoyo wamunthu. Chifukwa chake, kuwongolera bwino ndikuzindikira zomwe zatsalira za klorini ndizofunikira pakuwongolera madzi.
Pali mitundu ingapo ya chlorine m'madzi:
Klorini yotsalira (klorini yaulere): Chlorine mu mawonekedwe a hypochlorous acid, hypochlorite, kapena kusungunuka elemental chlorine.
Kuphatikiza klorini: Klorini mu mawonekedwe a chloramines ndi organochloramines.
Total klorini: Klorini kupezeka mu mawonekedwe a free residual klorini kapena kuphatikiza klorini kapena zonse ziwiri.
Kuti mudziwe za chlorine yotsalira ndi klorini yonse m'madzi, njira ya o-toluidine ndi njira ya ayodini idagwiritsidwa ntchito kwambiri m'mbuyomu. Njirazi ndizovuta kugwiritsa ntchito ndipo zimakhala ndi maulendo aatali osanthula (zomwe zimafuna amisiri aluso), ndipo sizingakwaniritse zofunikira pakuyezetsa mwachangu komanso pakufunidwa kwamadzi. zofunikira ndipo sizoyenera kusanthula pamasamba; Komanso, chifukwa o-toluidine reagent ndi carcinogenic, njira yotsalira klorini kuzindikira mu "Miyezo Ukhondo wa Madzi Kumwa" lofalitsidwa ndi Unduna wa Zaumoyo wa People's Republic of China mu June 2001 anachotsa o-toluidine reagent. Njira ya benzidine idasinthidwa ndi DPD spectrophotometry.
Njira ya DPD pakadali pano ndi imodzi mwa njira zolondola kwambiri zodziwira pompopompo chlorine yotsalira. Poyerekeza ndi njira ya OTO yodziwira chlorine yotsalira, kulondola kwake ndikwambiri.
DPD kusiyana kwa photometric kuzindikira Photometry ndi njira yowunikira ya chemistry yomwe nthawi zambiri imagwiritsidwa ntchito poyeza kuchuluka kwa chlorine yotsalira kapena chlorine yonse m'madzi. Njira imeneyi imatsimikizira kuchuluka kwa chlorine poyesa mtundu wopangidwa ndi mankhwala enaake.
Mfundo zazikuluzikulu za DPD photometry ndi izi:
1. Zomwe zimachitika: M'miyeso yamadzi, klorini yotsalira kapena klorini yonse imakhudzidwa ndi ma reagents apadera amankhwala (DPD reagents). Izi zimapangitsa kuti mtundu wa yankho usinthe.
2. Kusintha kwa mtundu: Pawiri yopangidwa ndi DPD reagent ndi klorini idzasintha mtundu wa njira yothetsera madzi kuchokera ku mtundu wopanda mtundu kapena wachikasu wowala mpaka wofiira kapena wofiirira. Kusintha kwa mtundu uku kuli mkati mwa mawonekedwe owoneka bwino.
3. Muyezo wa Photometric: Gwiritsani ntchito spectrophotometer kapena photometer kuyeza kuyamwa kapena kufalikira kwa yankho. Muyezo uwu nthawi zambiri umachitika pamlingo wina wake (nthawi zambiri 520nm kapena utali wina wa wavelength).
4. Kusanthula ndi kuwerengetsera: Kutengera kuchuluka kwa kuyamwa kapena kutulutsa kwamadzi, gwiritsani ntchito njira yokhotakhota kapena yokhazikika kuti mudziwe kuchuluka kwa klorini m'madzi.
DPD photometry nthawi zambiri imagwiritsidwa ntchito kwambiri pochiza madzi, makamaka poyesa madzi akumwa, mtundu wamadzi osambira komanso njira zopangira madzi m'mafakitale. Ndi njira yosavuta komanso yolondola yomwe imatha kuyeza msanga kuchuluka kwa chlorine kuti iwonetsetse kuti chlorine m'madzi imakhala mkati mwazoyenera kuchotsa mabakiteriya ndi tizilombo toyambitsa matenda.
Chonde dziwani kuti njira zowunikira zenizeni ndi zida zimatha kusiyana pakati pa opanga ndi ma laboratories, kotero mukamagwiritsa ntchito DPD photometry, chonde onani njira yowunikira komanso buku logwiritsira ntchito zida kuti muwonetsetse kulondola komanso kubwerezabwereza.
LH-P3CLO yoperekedwa pano ndi Lianhua ndi mita yotsalira ya chlorine yomwe imagwirizana ndi njira ya DPD photometric.
Kugwirizana ndi muyezo wamakampani: HJ586-2010 Ubwino wa Madzi - Kutsimikiza kwa Chlorine Yaulere ndi Total Chlorine - N, N-diethyl-1,4-phenylenediamine spectrophotometric njira.
Njira zoyezera madzi akumwa - Zizindikiro zopha tizilombo (GB/T5750,11-2006)
Mawonekedwe
1, Yosavuta komanso yothandiza, yothandiza pakukwaniritsa zosowa, kuzindikira mwachangu zizindikiro zosiyanasiyana komanso ntchito yosavuta.
2, 3.5-inch color color, mawonekedwe omveka bwino komanso okongola, mawonekedwe ogwiritsira ntchito kalembedwe, ndende ndikuwerenga molunjika.
3, Zizindikiro zitatu zoyezeka, zothandizira chlorine yotsalira, chlorine yotsalira yonse, ndi kuzindikira kwa chizindikiro cha chlorine dioxide.
4, 15 ma PC a ma curve omangidwira, kuthandizira kusanja kokhotakhota, kukwaniritsa zofunikira zamabungwe ofufuza asayansi, ndikusintha kumadera osiyanasiyana oyesera.
5, Kuthandizira kuwongolera kwa kuwala, kuwonetsetsa kuwala kowala, kukonza kulondola kwa zida ndi kukhazikika, komanso kukulitsa moyo wautumiki.
6, Kumangirira malire apamwamba, chiwonetsero chanzeru cha malire opitilira, kuyimba kuwonetsa mtengo wapamwamba, kuthamangitsidwa kofiira kupitilira malire.
