Ngokuhlolwa kweshubhu ye-Aijiren COD, umsebenzisi ngamunye angakwazi ukuthola kalula amanzi azwela kakhulu futhi anembile.

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.

I-COD Test Tube ekhiqizwe i-Aijiren inamandla angu-10ml, 12ml, kanye no-15ml. Ubukhulu buyi-16 mm. Ivamise ukusetshenziselwa ukuhlola izinga lamanzi futhi iqukethe ama-reagents awuketshezi. Isetshenziswa kakhulu embonini ye-petroleum kanye nokuhlaziywa kwamakhemikhali.
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.

Amashubhu okuhlola we-COD akhiqizwa i-Aijiren avame ukusetshenziselwa ukuhlolwa kombala wokugaya. Lolu hlobo lokuhlola lunezidingo eziphezulu ze-COD Test Tubes futhi lunobubanzi bezinhlelo zokusebenza. Imithi, i-petroleum, amakhemikhali, ikhwalithi yamanzi, njll. konke kudinga ukusebenzisa ukuhlolwa kwe-colorimetric yokugaya. ukuhlola. I-Aijiren's COD Test Tubes ingahlangabezana kahle nezimfuneko zezinto ezisetshenziswayo ekuhloleni kombala wokugaya ukudla.

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.

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 uhlolo lwe-COD lwenziwa njengenjwayelo kulabhorethri yezinsiza zamanzi nezinkampani zezimboni.

Ama-COD Tubetests asetshenzisiwe aqukethe i-sulfuric acid eqinile namanye amakhemikhali, ngakho-ke ama-reagents kufanele aphathwe ngokucophelela. Okuqukethwe kwepayipi kufanele kulahlwe ngokuhambisana nezidingo zeziphathimandla zendawo.

Ukuhlola amanzi e-Total Organic Carbon (TOC) akusabalulekile embonini yezemvelo. Ngezindlela zakamuva ze-USP, i-TOC manje isiyinkinga yanoma iyiphi imboni esebenzisa Amanzi Ahlanzekile Namanzi Omjovo. Izitsha ze-TOC ze-Aijiren Low Level zihlanzwa ngokukhethekile futhi zipakishwe ukuze kwehlise i-TOC ibe amazinga aphansi kakhulu ngangokunokwenzeka, iqinisekisa isizinda esiphansi sokuhlolwa kwakho.
Ishubhu yokuhlola ye-COD iqukethe umthamo oqondile we-reagent. Ngakho-ke, inani lamakhemikhali eleqile liyagwenywa futhi nokuphepha komsebenzi kuyathuthukiswa.

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.

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.

Isidingo somoya-mpilo wamakhemikhali siwukuhlola okubalulekile kokuhlola ikhwalithi yamanzi alahlwayo kanye namanzi angcolile ngaphambi kokuba akhishwe.

Ngakho-ke uhlolo lwe-COD lwenziwa njengenjwayelo kulabhorethri yezinsiza zamanzi nezinkampani zezimboni.

Ishubhu yokuhlola ye-COD engu-16mm Yokuthengisa Okushisayo Kwaselabhorethri

U-2mL wesampula wamanzi noma we-watse wengezwa eshubhuni yengilazi engu-16mm equkethe into evuselela ukugaya ukudla kanye ne-catalyst. Ishubhu imbozwe nge-polypropylene, ikepisi elayishiwe ye-PTFE futhi ishisiswe ku-block digester ku-150C amahora angu-2. I-chromium ye-Hexavalent ewolintshi yehliswa ibe yi-chromium e-trivalent eluhlaza okwesibhakabhaka. Ibanga lokuhlaziya lendlela ye-spectrophotometric ngu-5-150ppm (kukalwa ku-420nm).

Amashubhu okuhlola we-COD akhiqizwa i-Aijiren avame ukusetshenziselwa ukuthola isidingo samakhemikhali komoyampilo. Ingilazi esetshenziswe ku-COD Test Tubes ekhiqizwe i-Aijiren inokumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, futhi ingawavikela kahle amasampula ngaphandle kokuthinta imiphumela yokuhlola. Izinto zokusetshenziswa ze-Aijiren zingezekhwalithi ephezulu kanye nesipiliyoni sokukhiqiza Ngokuchichimayo, ngamanani omkhiqizo avumayo, ingumnikezeli wekhwalithi ephezulu wezinto ezisetshenziswayo zechromatographic.

Leli shubhu lokuhlola le-COD liklanywe ngokunemba nokusebenza engqondweni. Inesakhiwo esimangelengele esingamelana nobunzima bokuhlolwa kwe-COD, okuhlanganisa amazinga okushisa aphezulu kanye nokuchayeka kumakhemikhali ahlukahlukene.

I-Aijiren COD Test Tube yenziwe ngengilazi ye-borosilicate, enganciphisa izinguquko ze-pH kanye nokungcola okungase kudonswe engilazini ye-soda lime.  Ishubhu yokuhlola ukugaya kwengilazi ingasetshenziselwa ukuhlaziya e ...

*Incazelo: Igama lomkhiqizo: 16mm Ishubhu Lokuhlola Lokuhlaziya Amanzi Umthamo: 10-15ML, PTFE Septa yokuvalwa kweshubhu lokuhlola elingu-16mm Isikulufa Esimhlophe Sekhephu ye-Polycarbonate, Okuvalekile, 12mL Sula ishubhu lokuhlola...
Faka isikulufu ikepisi ngokuvikelekile ukuze uhlole ishubhu, ubambe ishubhu ngekepisi, faka ishubhu ebhodleleni lokuphepha futhi unyakazise

I-Aijiren COD Test Tube incane ngosayizi futhi ilula ngesisindo. Ingahlolwa ngaphandle kwanoma iyiphi enye impahla yaselabhorethri kanye nochwepheshe; kuthatha imizuzu engu-3-5 kuphela ukuhlola isampula, ngaphandle kwezinto ezengeziwe noma amathuluzi, futhi kulula ukuyisebenzisa.

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.
