Chlorine disinfectant inowanzo shandiswa uye inoshandiswa zvakanyanya mukuita disinfection yemvura yepombi, madziva ekushambira, tableware, etc. Zvisinei, mishonga ine chlorine-ine disinfectants inobudisa zvakasiyana-siyana-zvichigadzirwa panguva yekuuraya utachiona, saka kuchengetedzwa kwehutano hwemvura mushure mokunge. chlorination disinfection yakwezva kutarisisa kuri kuwedzera. Residual chlorine yemukati chiratidzo chakakosha chekuongorora kushanda kwekuuraya hutachiona hwemvura.
Kuti udzivise kudzokororwa kweakasara mabhakitiriya, mavhairasi uye mamwe tupukanana mumvura, mushure mekunge mvura yaiswa disinfectants nechlorine-ine disinfectants kwenguva yakati, panofanira kunge paine yakaringana yakasara chlorine mumvura kuve nechokwadi chekuenderera mberi. sterilization kugona. Nekudaro, kana iyo yakasara chlorine yemukati yakawandisa, inogona kukonzeresa kusvibiswa kwechipiri kwemhando yemvura, kazhinji inotungamira mukugadzirwa kwecarcinogens, kukonzera hemolytic anemia, nezvimwewo, ine zvimwe zvinokuvadza pahutano hwevanhu. Naizvozvo, kunyatso kudzora uye kuona zvakasara zveklorini zvakakosha mukurapa kwekupa mvura.
Mhando dzinoverengeka dzeklorini dziripo mumvura:
Residual chlorine (yemahara chlorine): Chlorine muchimiro che hypochlorous acid, hypochlorite, kana yakanyungudutswa elemental chlorine.
Yakasanganiswa chlorine: Chlorine muchimiro chekloramines uye organochloramines.
Total chlorine: Chlorine iripo muchimiro chemahara yakasara chlorine kana yakasanganiswa chlorine kana zvese.
Nekugadziriswa kweklorini yakasara uye yakazara chlorine mumvura, nzira ye-o-toluidine uye nzira yeiodine yakashandiswa zvakanyanya munguva yakapfuura. Idzi nzira dzinonetsa kushanda uye dzine marefu ekuongorora maitiro (inoda nyanzvi dzehunyanzvi), uye haigone kuzadzisa zvinodiwa nekukurumidza uye-pakuda kuyedzwa kwemhando yemvura. zvinodiwa uye hazvina kukodzera pa-site kuongororwa; uyezve, nekuti iyo o-toluidine reagent ine carcinogenic, iyo yakasara chlorine yekuona nzira mu "Hygienic Standards for Drinking Water" yakaziviswa neBazi reHutano rePeople's Republic of China muna Chikumi 2001 yakabvisa o-toluidine reagent. Iyo benzidine nzira yakatsiviwa neDPD spectrophotometry.
Nzira yeDPD pari zvino ndiyo imwe yenzira dzakarurama dzekuona nekukasira kwasara chlorine. Kuenzaniswa neOTO nzira yekuona yasara chlorine, huchokwadi hwayo hwakakwira.
DPD musiyano wephotometric yekuona Iyi nzira inosarudza chlorine concentration nekuyera ruvara runogadzirwa neimwe kemikari inogadzirisa.
Iwo musimboti weDPD photometry ndeaya anotevera:
1. Kuita: Mumienzaniso yemvura, chlorine yakasara kana kuti chlorine yose inopindirana nemakemikari chaiwo reagents (DPD reagents). Izvi zvinoita kuti ruvara rwemushonga uchinje.
2. Kuchinja kwemavara: Mushonga wakaumbwa neDPD reagent uye chlorine ichashandura ruvara rwemvura yemuenzaniso mhinduro kubva kune isina ruvara kana chiedza yero kusvika kune tsvuku kana yepepuru. Uku kushanduka kwemavara kuri mukati meiyo inooneka spectrum range.
3. Photometric kuyerwa: Shandisa spectrophotometer kana photometer kuyera kunyura kana kutumira kwemhinduro. Chiyero ichi chinowanzoitwa pane imwe wavelength (kazhinji 520nm kana imwe wavelength chaiyo).
4. Ongororo uye maverengero: Kubva pane kuyerwa kunyura kana kukosha kwekutamisa, shandisa mwero curve kana concentration formula kuti uone kuwanda kweklorini mumuenzaniso wemvura.
DPD photometry inowanzo shandiswa zvakanyanya mumunda wekurapwa kwemvura, kunyanya mukuyedza mvura yekunwa, mhando yemvura yekushambira uye maitiro ekugadzirisa mvura mumaindasitiri. Iyo nzira iri nyore uye yakarurama inogona kukurumidza kuyera kusanganiswa kweklorini kuti ive nechokwadi chokuti chlorine concentration mumvura iri mukati mehutano hwakakodzera kubvisa mabhakitiriya uye mamwe ma microorganisms anokuvadza.
Ndokumbira utarise kuti nzira dzekuongorora uye zviridzwa zvinogona kusiyana pakati pevagadziri nemarabhoritari, saka kana uchishandisa DPD photometry, ndapota tarisa kune chaiyo yekuongorora nzira uye chiridzwa chekushandisa bhuku kuti uone chokwadi uye kudzokorora.
Iyo LH-P3CLO parizvino yakapihwa neLianhua inotakurika yasara chlorine mita inowirirana neDPD photometric nzira.
Inoenderana neindasitiri chiyero: HJ586-2010 Hunhu hweMvura - Kusarudza Yemahara Chlorine uye Yese Chlorine - N, N-diethyl-1,4-phenylenediamine spectrophotometric nzira.
Yakajairika nzira dzekuyedza dzemvura yekunwa - Disinfectant zviratidzo (GB/T5750,11-2006)
