Mutengesi wePotassium Dichromate muSouth Africa

Chii Chinonzi Potassium Dichromate?

Potassium dichromate (K₂Cr₂O₇) ikristalo yakasimba yeorenji-tsvuku uye ndiyo inonyanya kushandiswa mukuongorora makemikari. Isimba guru re oxidizing rinoita zvinofanotaurwa mu acidic aqueous solution, zvichiita kuti ive yakakodzera kuongororwa kwehuwandu, kunyanya mukuenzanisa kwesimbi nemakemikari oxygen demand (COD) mukuyedzwa kwemhando yemvura. Magiredhi emaindasitiri anoshanda mukurapa pamusoro pemvura uye kugadzira makemikari.

Kuongorora Kemistri & Kuedzwa kweMvura

Potassium dichromate inoshandiswa senzira huru mu redox titrations nekuti yakagadzikana, yakachena kwazvo, uye haina hygroscopic. Ndiyo reagent inosarudzwa pakusarudza COD mukutarisa mvura yakasviba nezvakatipoteredza, uye pakuongorora cerimetric titration yesimbi. Marabhoritari ese ari kumaodzanyemba kweAfrica anoshandisa potassium dichromate mumabasa enguva dzose ekuongorora mvura, metallurgical, uye makemikari.

Kupenda Dehwe & Kudhaya Machira

Muindasitiri yematehwe, potassium dichromate inoderedzwa kuita chromium (III) kana paine organic acids kuti igadzire chrome tanning agent. Maitiro aya anoshandura matehwe asina kubikwa kuita ganda rakapfava, rinogara kwenguva refu. Semushonga wejira, inonamira chrome dyes zvakasimba kune fiber dzemvere, ichiburitsa mavara akadzika, asinganeti mukugadzirwa kwemakapeti nemachira akakuvara.

Kuomesa Maindasitiri & Kugadzira Mapuroteni

Potassium dichromate inoshanda semushonga wekuchengetedza uye mune mamwe ma pyrotechnic formulations. Mukugadzirwa kwemakemikari, inooxidizes alcohols, aldehydes, uye aromatic side-chains. Inoshandiswawo mukugadzira chromium oxide catalysts. Kurongedza kwakachengeteka, MSDS magwaro, uye data remitemo zvinopihwa pese pakutumira.
