Lapho sithola i-COD, lapho sithola isampula lamanzi elingaziwa, singaliqonda kanjani ngokushesha ibanga lokuhlushwa lesampula lamanzi? Ukuthatha ukusetshenziswa okungokoqobo kwezinsimbi zokuhlola izinga lamanzi kanye nama-reagents e-Lianhua Technology, ukwazi isilinganiso esilinganiselwe se-COD sesampula samanzi kungasisiza ukuthi sikhethe uhla olufanele kanye nama-COD reagents ukwenza inani lokubona linembe kakhudlwana, ngaleyo ndlela sinikeze ulwazi olwengeziwe lokulashwa kwendle okulandelayo. umsebenzi. Ukwesekwa kwedatha kwangempela nokwethembekile.
Okulandelayo, sizolandela izinyathelo zonjiniyela be-Lianhua Technology futhi sikufundise ukuthi ungakuqonda kanjani ngokushesha ukulinganiselwa kwe-COD kumasampula amanzi. Okokuqala, thatha amashubhu okuhlola ama-3 uwabeke endaweni yokubeka ishubhu yokuhlola, engeza u-2.5 mL wamanzi acwecwe kwelinye lamashubhu okuhlola, bese wengeza u-2.5 mL wesampula lamanzi ukuze ahlolwe kwamanye amashubhu okuhlola amabili. Bese wengeza i-DE reagent ye-Lianhua Technology COD kumashubhu okuhlola amathathu ngokulandelayo, unyakazise kahle futhi ubheke ukushintsha kombala wesampula yamanzi kumashubhu okuhlola. Sisebenzisa umbala ukuze sahlulele cishe ukugxiliswa kwe-COD kusampula yamanzi. Lapho umbala usondelana noluhlaza okwesibhakabhaka-oluhlaza, lapho ukugxila kukhulu, futhi okuphambene nalokho, umbala usondelana kakhulu nongenalutho, ukugxila kuncane. Ngokwalesi simiso, ezinye izinto ezitholwayo zingakwazi futhi ukwazi ukugxiliswa okulinganiselwe kwesampula yamanzi ngokuthuthukiswa kombala kokugcina kokuhlolwa. Ingabe usufundile?
Okungenhla kumayelana nendlela yokwahlulela ngokushesha uhla lokuhlushwa olulinganiselwe lwamasampula amanzi e-COD. Silandele futhi ufunde kabanzi mayelana nokuhlolwa kwekhwalithi yamanzi!
