Kwethulwa amashubhu wokuhlola we-COD 16mm wokuhlaziywa kwamanzi

Nov. 19, 2020

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

Le khasiI-COD test tubeKukhiqizwe yi-AIJIREN kuvame ukusetshenziselwa ukuhlolwa kwekhwalithi yamanzi. Ukuze uvumelane namamodeli ahlukene kanye nemikhiqizo yemishini, i-Aijiren yethule ishubhu lokuhlola le-Multi-usayizi we-COD. I-caliber ingumfaniswano 16mm, kepha osayizi bangama-9ml, 10ml, 12ml no-15ml. Ishubhu lokuhlola le-9mL COD linefulethi eliphansi, ishubhu lokuhlola le-10ml COD linefulethi eliphansi kanye ne-12ml kanye ne-15ml ne-cod test tubes inendawo eyindilinga.

I-TOC yisifinyezo sekhabhoni ephelele ye-organic. AIJIREN I-COD test tube Inikeza usizo olukhulu ekuhlaziyweni kwekhwalithi yamanzi, kanye ne-TOC test tube kungalinganisa i-organic carbon ukwenza kahle i-CORTE PRESPORTS I-TUBE TUBE, okuhlinzeka ngemiphumela yokuhlolwa okuphezulu ukuze uthole kalula imishini yelebhu kanye, okutholakele futhi kunembile kakhulu.

Le khasi I-COD test tube Kukhiqizwe yi-AIJIREn kuvame ukusetshenziselwa ukuhlolwa okufunwa kwamakhemikhali umoya-mpilo. Inqubo imi kanjena: 2ml wamanzi noma isampula yamanzi entsha yengezwa ku-16mm esikweni lesiko le-tube eliqukethe i-ejenti yokugaya kanye ne-catalyst. Mboza ishubhu nge-polypropylene layisha i-polypropylene tube futhi uyishise ku-block digerger ku-150 ° C amahora ama-2. I-Orange Hexavalnt Chromium incishiswa yaba yi-chromium eluhlaza eluhlaza. Uhla lokuhlaziya lweSpectrophotometry luyi-5-150ppm (kulinganiswe ngo-420nm).

Ukuhlolwa kwe-Chemin Oxygen (COD) kusetshenziswa kabanzi njengezilinganiso zokungcola kwe-organic ngokunquma inani le-oxygen elidingekayo kwisampula yokunciphisa izicelo (kufaka phakathi i-oxidant ethile esebenzisa i-oxidant ethile, kanye nokuncishiswa kwezinga lokushisa nesikhathi. 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. 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.
