Screw top tube

Ukuhlolwa kwe-COD kuyinkomba engcono engcono yokungcola kwe-organic emanzini angcolile wezimboni aqukethe ama-cyanides kanye nezinsimbi ezisindayo. Ukuhlolwa kwama-COD kunika impendulo ngokushesha ekushintsheni kwezimo ngaphambi kwezinkinga ezibucayi ukuthuthukisa. 

Kulolu vivinya i-realent engenalutho isetshenziswa esikhundleni samanzi ajwayelekile angenalutho okukhulunywa ngalo kwimiyalo yokusebenza ye-Photometer. I-Reagent Blank ilungiselelwe ngokungeza amanzi ansundu noma ahlanganisiwe kushubhu le-reagent bese egaya ishubhu ngendlela efanayo nakwesampula yamanzi.
Akudingekile ukulungiselela i-realent aff isikhathi ngasinye lapho ukuhlolwa kwenziwa. I-reagent engenalutho ishubhu ingalungiswa masonto onke futhi isetshenziswe kaninginingi nawo wonke amasampula alungiselelwe kusuka ku-batch efanayo yamashubhu e-reagent. I-Reagent Blank kufanele igcinwe ebumnyameni phakathi kokusetshenziswa.

Isidingo se-chemical oxygen isivivinyo esibalulekile sokuhlola ikhwalithi yama-affeunts kanye namanzi okungcola ngaphambi kokukhipha. Isivivinyo se-Chemical Oxygen (COD) sibikezela isidingo se-oksijini se-affluent futhi sisetshenziselwa ukuqapha kanye nokulawula ukukhishwa, nokuhlola ukusebenza kwezitshalo zokwelashwa. Umthelela wokukhishwa kwamanzi okuguqukayo noma kokungcola emanzini atholayo kubikezelwe yisidingo salo se-oksijini. Lokhu kungenxa yokuthi ukususwa komoya-mpilo emanzi emvelo kunciphisa amandla ayo okuqinisa impilo yasemanzini. Ukuhlolwa kwe-COD ngakho-ke kwenziwa njengendlela ejwayelekile ezindaweni zokusebenzela izinsiza zamanzi kanye nezinkampani zezimboni.

Ngokuhlolwa kwe-AIJiren COC TUBE, umsebenzisi ngamunye angenza kalula ukutholwa kwamanzi okubucayi kakhulu nokunembile.
Isikhathi esidingekayo senqubo yokulinganisa sifinyezwa kakhulu, ikakhulukazi ukuhlaziya okujwayelekile kanye nokulinganisa, ngenkathi kunciphisa kakhulu umthwalo.
I-COD test tube iqukethe umthamo oqondile we-reagent. Ngakho-ke, ukusungulwa kwamakhemikhali ngokweqile kugwenywa futhi ukuphepha komsebenzi kuyathuthuka.

Imininingwane yokuhlolwa kwesicelo se-oxygen chemin:

I-2ML yesampula yamanzi noma ye-watse yamanzi ingeziwe kwi-16mm esikweni lesiko ishubhu eliqukethe i-reagent yokugaya kanye ne-catalyst. Ishubhu liboshwe nge-polypropylene, i-PTFE layisha i-cap futhi lifudumele ku-block digerter ku-150c amahora ama-2. I-Chromium ye-Orange Hexavalnt yencishiswa ibe yi-chromium eluhlaza okotshani. Uhla lokuhlaziya lwendlela ye-spectrophotometric yi-5-150ppm (kulinganiswe ngo-420nm).

Ama-tubetes asetshenzisiwe aqukethe i-sulfuric acid namanye amakhemikhali, ngakho-ke ama-reagents kumele aphathwe ngokucophelela. Okuqukethwe yipayipi kufanele kuchithwe ngokuya ngezidingo zabaphathi bendawo.
Lawa mashubhu wokuhlola aqinisekisiwe nge-SGC. Lawa amashubhu angasetshenziswa kanye kuphela, ngakho-ke awakwazi ukusetshenziswa kabusha.

Ukuze usebenzise i-heater yedijithali yokuhlolwa kwe-COD, setha izinga lokushisa esibonisweni sedijithali ku-150 ° C. Akunandaba ne-akhawunti kufanele kusethwe emazingeni okushisa aphezulu kunalokho okucacisiwe ngoba lokhu kungadala ingozi ngokucindezela kwamashubhu akwakheka kumashubhu e-COD.

Ilungele imilovu namakhithi wokuhlola emakethe
Futhi ilungele amathuluzi nama-kits wokuhlola
Ama-vials afakwe kalula avulekile asuse ubungozi bokungcola okuwela
Nweba impilo eshalofini kuya eminyakeni emihlanu
Isetshenziselwa ukuhlolwa kwamanzi emoyeni; amanzi amdaka ezimboni kanye nokuhlolwa kokulawulwa kwenqubo; Ukuhlolwa kwamanzi emvelo

Vula i-COD test tube, uyibambe nge-angle futhi ungeze kancane
I-2.0 ml yesisombululo sesampula esenziwe njenge-reacreated kusuka kushubhu reaction ngaphandle kokuxuba ukuze izingqimba ezimbili ezihlukile
ayakhiwa.
I-Screw Cap ngokuphephile ekuhlolweni kwe-tube, bamba ishubhu nge-cap, indawo ye-tube ebhodleleni lokuphepha bese inyakaze
(Ukuqapha, ishubhu lokuhlola liyashisa). Beka ishubhu ebhlokini lokushisa. Qala uhlelo lokushisa.
Ngemuva kuka-2 h Susa ishubhu lokuhlola kusuka ku-Heating Block, vumela ukupholisa phansi ekushiseni kwegumbi bese unyakazisa ngobumnene
kaninginingi.
Hlanza ngaphandle kweshubhu lokuhlola nesilinganiso.
Lungisa i-photometer kuya ku-zero ngokusebenzisa inani elingenalutho "null"

Ukuhlolwa kwe-Chemin Oxygen (COD) kusetshenziswa kabanzi njengesilinganiso sokungcola kwe-oksintshi ngokunquma i-oxygen edingekayo ye-oxidation yezinhlobo ezincishisiwe kufaka phakathi i-ejenti ye-oxidic, ekhasini lokushisa lokushisa kanye nokuncishiswa kwesikhathi. Ukuhlolwa kwe-COD kuyinkomba engcono engcono yokungcola kwe-organic emanzini angcolile wezimboni aqukethe ama-cyanides kanye nezinsimbi ezisindayo. Ukuhlolwa kwama-COD kunika impendulo ngokushesha ekushintsheni kwezimo ngaphambi kwezinkinga ezibucayi ukuthuthukisa. Ama-Vials we-Lovibond's COD ahambelana nobabili uLovibond noHach® Colorimeters.
