I-Chlorine ingenye yezinkomba lapho ukuhlolwa kwekhwalithi yamanzi okuvame ukudinga ukunquma.
Muva nje, umhleli uthole impendulo evela kubasebenzisi: Lapho usebenzisa indlela ye-DPD ukukala i-Chlorine, iphunga ngokusobala iphunga elinamandla, kodwa ukuhlolwa akuzange kubonise umbala.Sinjani isimo?(Qaphela: Izimfuneko zemajini yesibulala-magciwane ziphezulu uma kuqhathaniswa)
Mayelana nalesi simo, ake sihlaziye nawe namuhla!
Okokuqala, indlela esetshenziswa kakhulu yokuthola i-chlorine i-DPD spectrophotometry.Ngokusho kwe-EPA: Uhlu lwe-chlorine oluyinsalela lwendlela ye-DPD luvamise ukuba ngu-0.01-5.00 mg/L.
Okwesibili, i-hypochlorous acid, ingxenye eyinhloko ye-chlorine yamahhala emanzini, inezakhiwo ze-oxidizing kanye ne-bleaching.Sebenzisa indlela ye-DPD ukukala i-chlorine esele emanzini: Uma okuqukethwe kwe-chlorine kusampula yamanzi kuphezulu kakhulu, ngemva kokuba i-DPD i-oxidized ngokuphelele futhi yathuthukiswa. , i-chlorine eyengeziwe izobonisa impahla ye-bleaching, futhi umbala uzobe u-bleached, ngakho-ke uzovela Lesi simo senkinga ekuqaleni kwesihloko.
Ngenxa yalesi simo, kunconywa izixazululo ezimbili ezilandelayo.
1. Uma usebenzisa indlela ye-DPD ukuthola i-chlorine, ungakwazi ukuhlambulula isampula lamanzi ngamanzi ahlanzekile ukuze i-chlorine ibe phakathi kwebanga lika-0.01-5.00 mg/L, bese wenza ukutholwa.
2. Ungakhetha ngokuqondile okokusebenza okuhlonza ukugcwala okuphezulu kwe-chlorine esele ukuze kubonwe.
