Imfuno yeoksijini yekhemikhali (COD): irula engabonakaliyo yomgangatho wamanzi asempilweni
Kwimekobume esihlala kuyo, ukhuseleko lomgangatho wamanzi likhonkco elibalulekileyo. Nangona kunjalo, umgangatho wamanzi awusoloko ubonakala, kwaye ufihla iimfihlelo ezininzi esingenakuzibona ngokuthe ngqo ngamehlo ethu. Imfuno ye-oksijini ye-Chemical (COD), njengeparameter ephambili kuhlalutyo lomgangatho wamanzi, ifana nomgaqo ongabonakaliyo ...Funda ngokugqithisileyo -
Ukumiselwa kobugxwayiba emanzini
Umgangatho wamanzi: Ukumiselwa kwe-turbidity (GB 13200-1991)" ibhekiselele kumgangatho wamazwe ngamazwe we-ISO 7027-1984 "Umgangatho wamanzi - Ukumiselwa kwe-turbidity". Lo mgangatho uchaza iindlela ezimbini zokumisela i-turbidity emanzini. Inxalenye yokuqala yi-spectrophotometry, ethi...Funda ngokugqithisileyo -
Iindlela zokufunyanwa ngokukhawuleza kwezinto eziqinileyo ezimisiweyo
Izinto eziqinileyo ezinqunyanyiswayo, njengoko negama lisitsho, ziyi-particle edada emanzini ngokukhululekileyo, idla ngokuba phakathi kwe-0.1 microns kunye ne-100 microns ngobukhulu. Zibandakanya kodwa azikhawulelwanga kwintlenga, udongwe, i-algae, i-microorganisms, i-molecular organic matter, njl., ukwenza umfanekiso onzima we-m...Funda ngokugqithisileyo -
Zeziphi iingxaki ezisombululwa sisixhobo se-COD?
Isixhobo se-COD sisombulula ingxaki yokulinganisa ngokukhawuleza nangokuchanekileyo imfuno ye-oksijini yeekhemikhali kwimizila yamanzi, ukuze kuqinisekiswe iqondo lokungcoliseka kwezinto eziphilayo emanzini. I-COD (imfuno ye-oksijini yeekhemikhali) sisalathisi esibalulekileyo sokulinganisa iqondo longcoliseko lwendalo emanzini...Funda ngokugqithisileyo -
Ukusetyenziswa kwe-ORP kunyango lwelindle
Imele ntoni i-ORP kucoceko lwelindle? I-ORP imele i-redox enokwenzeka kunyango lwelindle. I-ORP isetyenziselwa ukubonisa iimpawu ze-macro redox zazo zonke izinto kwisisombululo esimanzi. Okukhona kuphezulu amandla e-redox, amandla epropathi ye-oxidizing, kwaye esezantsi amandla e-redox, i-str ...Funda ngokugqithisileyo -
