I-chlorine eyinsalela isho ukuthi ngemva kokuba izibulala-magciwane ezine-chlorine zifakwe emanzini, ngaphezu kokudla ingxenye yenani le-chlorine ngokusebenzisana namagciwane, amagciwane, izinto eziphilayo, nezinto ezingaphili emanzini, ingxenye esele yenani le-chlorine. i-chlorine ibizwa ngokuthi i-chlorine esele. Ingahlukaniswa ibe i-chlorine eyinsalela yamahhala kanye ne-chlorine eyinsalela ehlanganisiwe. Isamba lalawa ma-chlorine amabili ayinsalela abizwa ngokuthi i-residual chlorine, engasetshenziswa ukukhombisa umphumela wokubulala amagciwane wemithombo yamanzi. Izikhungo ezifanele ezindaweni ezihlukahlukene zingakhetha ukuthola i-chlorine eyinsalela noma i-chlorine eyinsalela ngokwezindinganiso ezifanele kanye nezimo ezithile zemithombo yamanzi. Phakathi kwazo, i-chlorine eyinsalela yamahhala ngokuvamile iyi-chlorine yamahhala ngendlela ye-Cl2, HOCl, OCl-, njll.; i-chlorine eyinsalela ehlanganisiwe yi-chloramines NH2Cl, NHCl2, NCl3, njll. eyakhiwe ngemva kokusabela kwe-chlorine yamahhala nezinto ze-ammonium. I-chlorine eyinsalela esivame ukuyisho ngokuvamile ibhekisela ku-chlorine eyinsalela yamahhala.
I-chlorine eyinsalela/ingqikithi ye-chlorine eyinsalela inezidingo ezihlukene zamanzi okuphuza asekhaya, amanzi angaphezulu, kanye nendle yezokwelapha. Phakathi kwazo, i-“Drinking Water Sanitation Standard” (GB 5749-2006) idinga ukuthi inani le-chlorine elisele lamanzi embonini yeyunithi yokuphakela amanzi lilawulwe ku-0.3-4.0mg/L, kanye nokuqukethwe kwe-chlorine esele ekugcineni inethiwekhi yamapayipi akufanele ibe ngaphansi kuka-0.05mg/L. Ukugcwala kwe-chlorine eyinsalela emithonjeni yamanzi okuphuza amanzi asendaweni eyodwa kufanele ngokuvamile kube ngaphansi kuka-0.03mg/L. Uma ukugcwala kwe-chlorine eyinsalela kungaphezu kuka-0.5mg/L, kufanele kubikwe emnyangweni wokuphatha imvelo. Ngokwezihloko ezihlukene zokulahla kanye nezinkambu zokulahla indle yezokwelapha, izidingo ze-chlorine eyinsalela endaweni yokuphuma kwechibi lokuxhumana lokubulala amagciwane zihlukile.
Ngenxa yokuthi i-chlorine esele kanye ne-chlorine eyinsalela ayizinzile emanzini, amafomu akhona athinteka kalula yizici ezifana nezinga lokushisa nokukhanya. Ngakho-ke, ukutholwa kwe-chlorine esele kanye ne-chlorine eyinsalela ngokuvamile kuyanconywa ukuthi kutholwe ngokushesha endaweni yesampula ukuze kuqinisekiswe ukunemba kokutholwa. Izindlela zokuhlonza i-chlorine esele kanye ne-chlorine eyinsalela ephelele ihlanganisa "HJ 586-2010 Ukunqunywa kwe-chlorine yamahhala kanye nenani le-chlorine ekhwalithi yamanzi N,N-diethyl-1,4-phenylenediamine spectrophotometric indlela", indlela ye-electrochemical, indlela ye-reagent, njll. I-Lianhua Technology LH-CLO2M Portable Chlorine Meter ithuthukiswe ngokusekelwe ku-spectrophotometry ye-DPD, futhi inani lingatholwa ngomzuzu ongu-1. Isetshenziswa kabanzi ekuqaphelweni kwesikhathi sangempela kwe-chlorine eyinsalela kanye ne-chlorine eyinsalela ephelele ngenxa yokunemba kwayo kokutholakala nokusebenza kalula emsebenzini.
