Kusetshenziswa kanjani ishubhu lokuhlola i-COD ekuhlaziyweni kwamanzi

Nov. 20th, 2020

Amathegi: cod-vial I-16mm-cod-vial I-COD-test-tube I-COD-tube

Le khasiI-COD test tubeKukhiqizwe yi-AIJIREN kuvame ukusetshenziselwa ukuhlolwa kwe-oxygen (i-COD) yamakhemikhali, kanye nokuhlolwa kwe-COD kusebenzisa i-oxidant ethile ku-oxidizetation izinto (kufaka phakathi i-organics) kwisampula yamanzi. Njengoba izinga lokushisa nesikhathi sehla, ukuhlolwa kudinga le ndlela kuvame ukusetshenziswa kabanzi njengezilinganiso zokungcola okungokwemvelo.

Ukuhlolwa kwesicelo se-oxygen chemin kungakhombisa kangcono ukungcoliswa kwezinto eziphilayo kumanzi angcolile wezimboni aqukethe ama-cyanide kanye nezinsimbi ezisindayo. Ukuhlolwa kwe-COD kungaphendula ngokushesha ekushintsheni kwezimo ngaphambi kokuba kuphakame izindaba ezibucayi. Nge-aijiren I-COD test tube, Umsebenzisi ngamunye angenza kalula ukutholwa kwamanzi okubucayi kakhulu nokunembile.

Ngaphezu kwalokhu, isidingo se-chemical oxygen nakho kuvivinywa okubalulekile ukuhlola ikhwalithi yamanzi amdaka kanye namanzi angcolile ngaphambi kokukhipha. Ukuhlolwa kwe-Chemical Oxygen (COD) kungabikezela isidingo se-oxygen yamanzi angcolile, okungasetshenziswa ukuqapha nokulawula ukuphuma nokulawula ukukhishwa kwezitshalo zokwelashwa.

Ngezinyathelo ezinemininingwane zokuhlolwa kwesifutho se-oxygen chemin, okokuqala engeza 2 ml wamanzi noma isampula yamanzi entsha ku-16mm I-COD test tube equkethe i-agent yokugaya kanye ne-catalyst. Mboza ishubhu nge-polypropylene layisha i-polypropylene tube futhi uyishise ku-block digerger ku-150 ° C amahora ama-2. I-COD test tube ekhiqizwa yi-AIJIREn ifakwe umthamo oqondile wama-reagents.

Kuyafaneleka ukugcizelela ukuthi lezi I-COD test tube ingasetshenziswa kuphela kanye futhi ayikwazi ukusetshenziswa kabusha. Ama-tubemetest asetshenzisiwe aqukethe i-sulfuric acid eqinile namanye amakhemikhali, ngakho-ke ama-reagents kumele aphathwe ngokucophelela. Amakhemikhali epayipini kufanele achithwe ngokuya ngezidingo zabaphathi bendawo. Lawa mashubhu wokuhlola adlulise isitifiketi se-SGC.

Okwedlule:

Kwethulwa amashubhu wokuhlola we-COD 16mm wokuhlaziywa kwamanzi

Olandelayo:

I-24mm Purge futhi ibambe ama-vials ohlelweni lwe-TOC
