COD Test Reagent
Cov ntaub ntawv yooj yim
Lub npe:COD Test Reagent
Lwm lub npe:Tshuaj lom neeg xav tau reagent; COD digestion reagent
Yam khoom:Pre-dosed dichromate reagent rau kev txiav txim siab COD (composite reagent)
Txoj kev:Dichromate digestion txoj kev (GB / T 11914 / HJ 828)
Kev sib xyaw:Potassium dichromate, sulfuric acid, nyiaj sulfate (catalyst), mercuric sulfate (chloride masking agent)
2. Lub cev thiab tshuaj lom neeg Cov khoom
- Qhov tsos:Amber rau daj digestion tov
- Kev ntsuas txoj cai:Hauv nruab nrab acidic, poov tshuaj dichromate oxidizes organic teeb meem hauv cov qauv dej hauv qab nyiaj sulfate catalysis; Tom qab kaw lub plab zom mov, cov seem seem lossis txo cov chromium hom raug ntsuas spectrophotometrically.
- Kev ruaj ntseg:Khaws kaw, hauv qhov chaw txias thiab tsaus
3.Main Functions and Applications (Nws yog dab tsi siv?)
- Kev saib xyuas dej zoo (kev siv tseem ceeb):Siv los txiav txim siab cov tshuaj oxygen xav tau (COD) ntawm cov dej, qhov ntsuas tseem ceeb rau kev ntsuas cov pa phem. COD yog ib qho tseem ceeb tshaj plaws nyob rau hauv kev ntsuam xyuas dej zoo, kev ua raws cai thiab kev ua kom muaj kuab paug.
- Daim ntawv thov kev lag luam:Dav siv los ntawm cov chaw saib xyuas ib puag ncig, cov chaw kho dej khib nyiab, kev tswj xyuas cov dej ntws tawm, kev saib xyuas qhov chaw / dej hauv av thiab thib peb- cov chaw kuaj sim.
- Ntau yam kev xaiv:Tsawg ntau 3-150 mg / L rau cov dej saum npoo av, dej haus thiab cov dej tsis huv; siab ntau 20-1500 mg / L rau cov dej khib nyiab dav dav; ultra-siab ntau 200–15000 mg/L rau siab -cov dej khib nyiab (nrog rau kev ua kom zoo).
- Qhov zoo:Ua ntej-dosed vials ua kom yooj yim, nrawm nrawm thiab raug, rov tsim dua cov txiaj ntsig nrog kev tuav tsawg, ua raws li GB/T 11914 thiab HJ 828.
4.A Benchmark-Level Industrial Masterpiece - A Meticulously Crafted "Npaj-rau-Siv"DejZoo Reagent!
Pre-dosed vials tau npaj siv, ua kom muaj kev ua haujlwm yooj yim thiab nrawm nrawm.
Tag nrho cov kev pab them nqi (3–150, 20–1500 thiab 200–15000 mg/L) ua tau raws li cov qauv dej ntawm txhua qib concentration. Ua raws li GB / T 11914 thiab HJ 828, xa cov txiaj ntsig raug thiab rov tsim dua.
"Qhov koj pom yog qhov koj tau txais" - txhua lub nkoj nrog daim ntawv pov thawj tiav ntawm kev tshuaj xyuas.
