Isicelo:

I-Potassium Dichromate (CAS: 7778-50-9) ine-oxidation eyomeleleyo kunye ne-corrosion, kwaye inokuxutywa kunye ne-agent yokunciphisa, izinto eziphilayo, izinto ezinokutsha okanye umgubo wesinyithi ukwenza umxube oqhumayo, onokubangela ukutsha okanye ukuqhuma ngokuxubha, ukungcangcazela okanye impembelelo. .
I-Potassium Dichromate, iyabola ukukhulula ioksijini kubushushu obumhlophe bobushushu, ine-oxidation eyomeleleyo, iyityhefu kunye ne-carcinogenic eyomeleleyo ye-oxidizing agent.Ihlelwa njengeqela I-carcinogen yi-Arhente yaMazwe ngaMazwe yoPhando ngoMhlaza (IARC) kwaye inokubamba umlilo xa ibonakaliswe kwizinto ezinokutsha.Ngenxa yokuba i-Potassium Dichromate ineepropati eziqinileyo ze-oxidizing phantsi kweemeko ze-acidic, idla ngokusetyenziswa kwilabhoratri ukulungisa isisombululo sokuhlamba i-chromic acid (umxube wesisombululo se-potassium dichromate kunye ne-sulfuric acid egxininisiweyo) ukuhlamba izixhobo zeglasi zemichiza ukususa ukungcola kwiindonga. inqanawa.Emva kokusetyenziswa, i-lotion iyatshintsha ukusuka kubomvu omnyama ukuya eluhlaza, kwaye i-lotion ayiyi kusebenza.I-Potassium dichromate iphinda isetyenziswe kwi-chemistry yohlalutyo, esetyenziswa ngokuqhelekileyo ukumisela ubungakanani be-hydrogen sulfuric acid, i-sulfurous acid, i-ion ye-ferrous kunye nokunye.Ekufudumeni, i-potassium dichromate inokuphinda idibanise i-hydrochloric acid egxininisiweyo, ukukhululwa kweklorini.
Isetyenziswe kwimveliso ye-chrome alum, iChromium oxide eluhlaza, i-pigment ye-chrome etyheli, i-electrode, i-inki yokuprinta, ikwasetyenziswa njenge-agent yokutshisa, i-enamel colorant, ukuprinta kunye ne-Dyeing mordant esetyenziswa kwimveliso ye-chrome alum, i-chrome oxide eluhlaza, i-chrome pigment emthubi.Ishishini le-enamel kunye nomgubo walo omde, isanti yequartz kunye nolunye umgubo oxutyiweyo we-enamel, njengombala oluhlaza.Ukulungiselela imatshisi Intloko Medicine, ukusuka indima oxidation kunye nokufuma.Isetyenziswa njenge arhente yokutshisa ulusu olukhanyayo.Ukudaya kweMordant kunye nokuprinta kusetyenziswa njenge-mordant.Iziqholo ezenziweyo zalungiselelwa ukusetyenziswa njengezinto ezixoxisanayo.Isetyenziselwa ukudibanisa i-electrode, inki yokuprinta, i-metal passivation.Isetyenziswa njenge-oxidants kunye ne-catalysts kwi-organic synthesis kunye nemathiriyeli ekrwada kumayeza.
Isetyenziselwa ukwenza imichiza yechromium, i-mordant, i-inki, iglasi, i-perfume, i-pigment, i-ceramics, i-varnish, iziqhushumbisi, amayeza, njl.
Isetyenziswe njenge-oxidant, i-potassium chrome alum kunye nereferensi yokulungiswa kwee-reagents zamakhemikhali
ukulinganisa izisombululo ezisemgangathweni zesodium thiosulfate.Uhlalutyo lwe-drop of chlorine, i-oxidants, i-Chromatography Reagents, i-organic synthesis.Ukusebenza kwesibindi kunye nesalathisi se-gallbladder silinganiswe.Isitulo, njl.
Isetyenziswa njengereferensi yereferensi, i-redox titrant, i-chromatography reagent kunye ne-oxidant, ikwasetyenziswa kwi-organic synthesis.

7778-50-9 - Ukhuseleko:

Impuku yomlomo LD o: 190mg/kg.I-Chromium ngumthombo wovelwano, kwaye i-chromium enehexavalent iyacaphuka kwaye iyadleka.Emva kokuphefumla kunokuvela ukuvutha kokuphefumula, isifuba, izilonda ze-chromium.Iyacaphukisa kakhulu ulusu.Uphononongo lwe-IARC carcinogenicity lubhalwe kakuhle.Le nto inokuba yingozi kwindalo, kwaye ingqalelo ekhethekileyo kufuneka ihlawulwe kumzimba wamanzi.Abasebenzi kufuneka bakhuselwe kakuhle, ukuba bachukumise ngengozi amehlo, kufuneka bahlambe ngokukhawuleza ngamanzi amaninzi ahambayo.Indawo yokusebenza kufuneka ibe neemeko ezilungileyo zokungenisa umoya.Gcina kwindawo epholileyo, eyomileyo, isitya kufuneka sivalwe ukuthintela ukufuma.Gwema ukugcinwa ngokubambisana kunye nokuthutha ngezinto eziphilayo, izinto ezinokutsha, ii-agent zokunciphisa, i-oxides kunye ne-acids.

Ugcino kunye neempawu zoThutho:

Indawo yokugcina ingena umoya kwaye yomiswe kwiqondo lokushisa eliphantsi;Ilula kwaye kulula ukuyikhupha;Idityaniswe ne-organic matter, i-reductant, isulfure kunye ne-phosphorus izinto ezinokutsha, ukugcinwa okwahlukileyo kokutya okukrwada.
