Lelei Fa'atau oloa Siisii ​​Saina o Chromic Acid Flakes

fa'amatalaga puupuu:

Chromic acid o le vaifofo fa'amama masani lea e fa'aaogaina ile falesu'esu'e.E iai uma le acidity ma le oxidizability.E mafai ona aveese le palapala ma mea e le mafai ona faʻaaogaina i luga o puipui i totonu ma fafo o mea faʻataʻitaʻi.

Auala su'esu'e

Fuafuaga o le chromic acid i totonu o le ea: o le faʻataʻitaʻiga na aoina i le faamama, faʻamavae i le sulfuric acid, ona fuafua lea e Colorimetry (NIOSH method) pe a uma ona faʻaopopo le diphenylcarbazide.

Fuafuaga ole chromic acid o lo'o i totonu ole vai: ole fa'ata'ita'iga e maua mai ma fa'amautu ile atomic absorption spectrometry po'o colorimetry.

Auala lafoa'i otaota: a mae'a le fa'aitiitiga o vaila'au, o le sua o otaota o le chromic acid e liu i le chromium trivalent, ma o le tau o le pH o le vaifofo e fetu'una'i e fausia ai le timuga, ma o le palapala o lo'o fa'atumuina e pei o otaota vaila'au.

Faamoemoega

Chromic acid o le vaifofo fa'amama masani lea e fa'aaogaina ile falesu'esu'e.E iai uma le acidity ma le oxidizability.E mafai ona aveese le palapala ma mea e le mafai ona faʻaaogaina i luga o puipui i totonu ma fafo o mea faʻataʻitaʻi.E masani lava, o le vaifofo fufulu e maua e ala i le faaopoopoina o le potassium dichromate i totonu o le acid sulfuric concentrated, ae o le hexavalent chromium e afaina ai le siosiomaga, ma o nisi taimi o le a faaleagaina ai le meafaigaluega i le siosiomaga malosi malosi, o lea ua faaitiitia ai le faaaogaina o le chromic acid vaifofo.

Chromic acid e mafai ona faʻaaogaina e fai ma oxidant.Le tele o mea fa'aola e mafai ona fa'ama'iina e le chromic acid, ma le tele o vaila'au fa'avae chromium hexavalent ua fausia.Jones reagent: vaifofo vai o le chromic acid, sulfuric acid ma le acetone, lea e mafai ona faʻamaʻi ai le ava malosi muamua ma le lua i vailaʻau carboxylic tutusa ma ketone e aunoa ma le aʻafiaina o fusi e leʻi tumu.Pyridinium chlorochromate: saunia mai le chromium trioxide ma pyridine hydrochloride, e mafai ona faʻamaʻiina le ava malosi i le aldehyde.Collins reagent: fa'aopoopoina ole chromium trioxide ma pyridine.

Chromic acid e mafai foi ona faʻaaogaina mo le faʻapipiʻiina o le chromium, chromium uʻamea maualuga-mama, pigmenti, mordant, vailaʻau ma le koale faʻafesoʻotaʻi, faʻapea foʻi ma le gaosiga o nisi glazes ma tioata lanu.
