Xa sifumanisa i-COD, xa sifumana isampula samanzi esingaziwayo, njani ukuqonda ngokukhawuleza uluhlu olusondeleyo lwesampulu yamanzi? Ukuthatha ukusetyenziswa okusebenzayo kwezixhobo zokuvavanya umgangatho wamanzi we-Lianhua Technology kunye ne-reagents, ukwazi ukuba i-COD yoxinaniso lwe-COD yesampuli yamanzi inokusinceda sikhethe uluhlu olufanelekileyo kunye ne-COD reagents ukwenza ixabiso lobhaqo oluchaneke ngakumbi, ngaloo ndlela ukubonelela ngolwazi oluthe kratya lokunyanga i-lindle elandelayo. umsebenzi. Inkxaso yokwenyani kunye nethembekileyo yedatha.
Okulandelayo, siya kulandela amanyathelo eenjineli zeTekhnoloji ye-Lianhua kwaye sikufundise ukuba uqonde njani ngokukhawuleza ukuxinwa kwe-COD kwiisampuli zamanzi. Okokuqala, thatha iityhubhu zokuvavanya ezi-3 kwaye uzibeke kwi-rack tube rack, yongeza i-2.5 mL yamanzi adibeneyo kwenye yeetyhubhu zokuvavanya, kwaye udibanise i-2.5 mL yesampuli yamanzi ukuze ivavanywe kwezinye iityhubhu ezimbini zokuvavanya. Emva koko yongeza i-DE reagent ye-Lianhua Technology COD kwiityhubhu zovavanyo ezintathu ngokulandelelana, xukuxa kakuhle kwaye ujonge utshintsho lombala wesampulu yamanzi kwiityhubhu zovavanyo. Sisebenzisa umbala ukugweba ukuxinwa okusondeleyo kwe-COD kwisampuli yamanzi. Okukhona umbala ukufutshane noluhlaza okwesibhakabhaka, kokukhona ugxininiso olukhulu, kwaye ngokuphambanayo, umbala ukufutshane ukuba ungabikho, kokukhona ugxininiso luncinci. Ngokwalo mgaqo-siseko, ezinye izinto zokubona zingakwazi kwakhona ukuxinana kwesampulu yamanzi ngokuphuhliswa kombala wokugqibela kovavanyo. Ngaba ufundile?
Oku ngasentla malunga nendlela yokugweba ngokukhawuleza uluhlu olusondeleyo lweesampulu zamanzi e-COD. Silandele kwaye ufunde ngakumbi malunga novavanyo lomgangatho wamanzi!
