Sodium Dichromate acts as a medium for producing other chromium compounds such as chromic anhydride,
potassium dichromate, and aluminium dichromate among others.
Dr Verma said the study found that the
potassium dichromate chemical, a major reason for skin allergies, was present in most of the samples.
Compound Molecular formula Sodium hypochlorite solution 40% NaClO Potassium permanganate KMn[O.sub.4] Ferric chloride Fe[Cl.sub.3]*6[H.sub.2]O Copper sulfate pentahydrate CuS[O.sub.4]*5[H.sub.2]O Glutaraldehyde solution (Grade I, [C.sub.5][H.sub.8][O.sub.2] 25% in [H.sub.2]O)
Potassium dichromate [K.sub.2][Cr.sub.2][O.sub.7] Compound Function on desalination process by RO Sodium hypochlorite solution 40% Disinfectant and oxidant chemical Potassium permanganate Oxidant chemical Ferric chloride Coagulant and flocculant chemical Copper sulfate pentahydrate Algaecide Glutaraldehyde solution (Grade I, Non-oxidizing biocide 25% in [H.sub.2]O)
Potassium dichromate As reference substance Table 2.
Patch testing results in Table I show that West Virginia has comparable rates of tested contact dermatitis allergens to the rest of the United States with exceptions of higher amounts of mercapto mix and
potassium dichromate. Mercapto mix is a common rubber additive (9), and
potassium dichromate is used in cement-based construction and chemical processing.
The allergens used included the following 20 allergens: control (petrolatum),
potassium dichromate 0.5%; neomycin sulphate 20%; cobalt chloride 1%; benzocaine 5%; formaldehyde 1%; paraphenylenediamine base 0.1%; parabens 15%; nickel sulphate 5%; colophony 20%; mercaptobenzothiazole 2%; nitrofurazone 1%; epoxy resin 1%; fragrance mix 8%; chlorocresol 1%; wool alcohol 30%; balsam of Peru 25%; thiuram mix 1%; black rubber mix 0.6%; Parthenium.
Focusing on the latter, they explain to professional and amateur woodworkers such aspects as preparing the wood for color, ammonium hydroxide for fuming,
potassium dichromate, introduction to natural dyes, logwood, grain filling, and wire brushing.
Soil organic matter was estimated by oxidation with known volume of acidified
potassium dichromate, the residual of which was titrated against 1 N ferrous sulfate by using diphenylamine indicator (Moodie et al., 1959).
Delayed patch test reactions after 5 days include metals (gold
potassium dichromate, nickel, and cobalt), topical antibiotics (neomycin and bacitracin), and topic corticosteroids.
Potassium Dichromate CAS 7778-50-9 (sunset 21-9-17)
Delayed patch-test reactions after 5 days include metals (gold
potassium dichromate, nickel, and cobalt), and topical antibiotics (neomycin and bacitracin) as well as topic corticosteroids.
NTP also generated other scientific products related to CrVI that preceded its drinking water studies: a) a series of three final reports on the reproductive effects of
potassium dichromate administered in the diet in rodents (NTP 1996a, 1996b, 1997) and b) the NTP "Report on Carcinogens" listing of CrVI compounds as "known to be human carcinogens" since 1980 (NTP 2014d).
