Ishubhu yokuhlola yekhwalithi ephezulu ye-COD iyathengiswa

Ishubhu le-COD elihlinzekwe i-Aijiren lisebenzisa ingilazi yekhwalithi ephezulu, engasebenzi kahle kakhulu futhi ngeke isabele ngezinto ezivuselelayo. Ngokuhlolwa kweshubhu ye-Aijiren COD, isikhathi esidingekayo senqubo yokulinganisa sifinyezwa kakhulu, ikakhulukazi ekuhlaziyeni okujwayelekile kanye nesilinganiso sochungechunge, okunciphisa kakhulu umsebenzi.
I-Aijiren isebenzisa izinto zokusetshenziswa zekhwalithi ephezulu ukwenza Ishubhu Lokuhlola elingu-16mm Lokuhlaziya Amanzi. Ukwaneliseka nokudumisa kwekhasimende kwenze i-Aijiren yaba ngenye yabakhiqizi abakhulu baselabhorethri abasebenzisekayo eningizimu yeChina. Okokuqala, i-Aijiren izogcina inhloso yokuqinisekisa ikhwalithi ye-16mm Test Tube Yokuhlaziya Amanzi.

Ukuhlola i-COD kuyinkomba engcono kakhulu yokungcoliswa kwemvelo emanzini angcolile embonini aqukethe ama-cyanides nezinsimbi ezisindayo. Ukuhlola i-COD kunikeza impendulo esheshayo ezimweni ezishintshayo ngaphambi kokuba kuvele izinkinga ezibucayi.

I-Test Tube yitemu elingasho izinto ezihlukene kuye ngomongo. Ngomongo wesayensi, ishubhu lokuhlola ingilazi eyisilinda noma ishubhu lepulasitiki elisetshenziselwa ukubamba futhi kuxube amanani amancane oketshezi ngesikhathi sokuhlolwa kulabhorethri. Isetshenziswa kakhulu ku-chemistry, biology, kanye nezinye iziyalo zesayensi.
Ekhiqizwe ku-Aijiren yengilazi ye-borosilicate yekhwalithi ephezulu kakhulu yoHlobo loku-1, amashubhu ethu okuhlola afaka izihloko ezinentambo nezingezansi eziyindilinga. Lawa mashubhu okuhlola isikulufa esindayo anobude obujulile obungu-415 GPI...

Ukuhlolwa kwe-tube kokuhlaziywa kwe-photometric kukholisa ngokuphathwa kwawo kalula ngakho-ke kuyinketho yokuqala yokuhlaziywa kwenqubo, ilabhorethri kanye nenqubo. Ubuningi bokunemba nokunemba kunikezwa emiphumeleni yokulinganisa ngenxa yama-reagents afakwe umthamo wangaphambilini ku-16mm cuvettes nama-reagents engeziwe.

Ishubhu yokuhlola ye-Aijiren enentambo ye-COD ingafakwa ngokuzithandela ngebhodi lokubhala, elilungele ukumakwa kwepensela. Futhi isekela amalogo ngokwezifiso. I-COD Test Tube ekhiqizwe ngu-Aijiren ingaba...

I-COD Test Tube yenziwe ngengilazi ye-borosilicate, enganciphisa izinguquko ze-pH kanye nokungcola okungaphuma engilazini ye-soda-lime. Ishubhu yokuhlola ukugaya ingilazi ingasetshenziselwa ukuhlaziya emazingeni okushisa angaphezu kuka-130 degrees Celsius. Yenziwe ngesitoreji selabhorethri ngezinhloso ezijwayelekile ezahlukahlukene futhi ingabamba cishe noma yini.

Ukuhlolwa kwe-Chemical Oxygen Demand (COD) kusetshenziswa kabanzi njengesilinganiso sokungcoliswa kwezinto eziphilayo ngokunquma inani le-oxygen edingekayo ukuze kufakwe i-oxidation yezinhlobo ezincishisiwe ezihlanganisa izinto eziphilayo, kusampula yamanzi kusetshenziswa i-oxidizing ejenti ethile, izinga lokushisa kanye nokunciphisa isikhathi. Ukuhlolwa kwe-COD kuyinkomba engcono kakhulu yokungcola kwemvelo emanzini angcolile ezimbonini aqukethe ama-cyanide nezinsimbi ezisindayo. Ukuhlolwa kwe-COD kunikeza impendulo esheshayo ezimeni ezishintshayo ngaphambi kokuba kuthuthuke izinkinga ezibucayi. Izitsha ze-COD zika-Lovibond ziyahambisana nama-colorimeter OKUMBILI we-Lovibond ne-Hach®.

Ngokuhlolwa kweshubhu ye-Aijiren COD, umsebenzisi ngamunye angakwazi ukuthola kalula amanzi azwela kakhulu futhi anembile. Isikhathi esidingekayo senqubo yokulinganisa sifinyezwa kakhulu, ikakhulukazi ekuhlaziyeni okujwayelekile kanye nesilinganiso sochungechunge, kuyilapho kunciphisa kakhulu umsebenzi.

Ngomqondo obanzi, i-“Test Tube” ingaphinda ibhekisele esiteshini se-YouTube esibizwa ngokuthi “TestTube,” okuyisiteshi esidumile sesayensi nezemfundo esiphethwe yi-Discovery Digital Networks. Lesi siteshi sihlanganisa izihloko eziningi ezihlanganisa isayensi, ubuchwepheshe, umlando, namasiko, futhi sihlinzeka ngamavidiyo afundisayo najabulisayo kubabukeli.

Akudingekile ukulungisa i-reagent engenalutho njalo lapho ukuhlolwa kwenziwa. Ishubhu elingenalutho le-reagent lingase lilungiswe masonto onke futhi lisetshenziswe ngokuphindaphindiwe nawo wonke amasampuli alungiselelwe kusukela kuqeqebana lamashubhu asebenzayo. I-reagent engenalutho kufanele igcinwe ebumnyameni phakathi kokusetshenziswa.

Kuyaqapheleka ukuthi uma ama-COD Tubetests asetshenzisiwe aqukethe i-sulfuric acid eqinile namanye amakhemikhali, ama-reagents kufanele aphathwe ngokucophelela. Izinto ezisepayipini kufanele zilahlwe ngokuhambisana nezidingo zeziphathimandla zendawo. Lawa mashubhu angasetshenziswa kanye kuphela futhi awakwazi ukuphinda asetshenziswe.
Kulokhu kuhlolwa kusetshenziswa i-reagent engenalutho esikhundleni sendawo evamile engenalutho yamanzi okukhulunywe ngayo emiyalweni evamile yokusebenza kwe-photometer. I-reagent blank ilungiswa ngokungeza amanzi akhishwe i-deionised noma a-distilled kushubhu le-reagent bese kugaywa ishubhu ngendlela efanayo neyesampula yamanzi.

Isidingo somoya-mpilo wamakhemikhali siwukuhlola okubalulekile kokuhlola ikhwalithi yamanzi alahlwayo kanye namanzi angcolile ngaphambi kokuba akhishwe. Ukuhlolwa kweChemical Oxygen Demand (COD) kubikezela isidingo somoya-mpilo kumfucumfucu futhi isetshenziselwa ukuqapha nokulawula okuphumayo, kanye nokuhlola ukusebenza kwezitshalo zokwelashwa. Umthelela wokuchitheka kwamanzi angcolile noma angcolile emanzini atholwayo ubikezelwa ngesidingo sawo somoya-mpilo. Lokhu kungenxa yokuthi ukukhishwa komoya-mpilo emanzini emvelo kunciphisa amandla awo okulondoloza impilo yasemanzini. Ngakho-ke ukuhlolwa kwe-COD kwenziwa njengenjwayelo kumalabhorethri ezinsiza zamanzi nezinkampani zezimboni.

Ishubhu yokuhlola ingilazi isitsha esiyisilinda esenziwe ngengilazi esivame ukusetshenziswa kulabhorethri yesayensi ukubamba, ukuxutshwa, nokushisisa amanani amancane oketshezi noma izinto eziqinile. Amashubhu okuhlola avamise ukuvuleka ekugcineni futhi anendawo eyindilinga noma evuleke kancane. Ziza ngosayizi abahlukahlukene, kusukela kumasentimitha ambalwa kuya kumasentimitha amaningana ubude.

I-TOC isifinyezo se-Total Organic Carbon. I-TOC Direct Method evela ku-Aijiren inikeza izindlela ezithembekile nezisebenzayo zezindawo zokuhlanza amanzi ukuze zivame ukukala ikhabhoni ephilayo ukuze kuthuthukiswe izinqubo zokwelashwa. Esikhundleni sokuthenga umhlaziyi we-TOC obizayo, ongokwesiko noma ukhiphe izinqumo ze-TOC elabhorethri yenkontileka, le ndlela inganikeza imiphumela ye-TOC - ngokunembile futhi engabizi - khona kanye endaweni yakho, futhi ngaphandle kwanoma iyiphi imfucuza eyingozi.\/p>
