EC number: 237-875-5
CAS number: 14038-43-8
The half life of hydrolysis of test
chemical Prussian blue (CAS no. 14038-43-8) was determined to be 1000
years so it is concluded that test test chemical prussin blue has
In accordance with column 2 of Annex VII of
the REACH regulation, testing for this end point is technically not
feasible and does not need to be conducted since the test prussian blue
Transport and distribution:
Adsorption:The target chemical
Prussian blue is strongly adsorbed to geolite. Goethite is common
component of soil.
The target chemical Prussian blue is
hydrolyzed at higher pH values, the liberated hexacyanoferrate ions are
strongly sorbed at the iron oxide hydroxides that already exist in the
soil or that have just been formed by hydrolysis of the Prussian blue.
The results obtained indicate that the
interaction of Prussian blue colloids and of dissolved hexacyanoferrate
ions with goethite can strongly retard the transport processes of these
compounds in soils. These processes help to immobilize Prussian blue in
soils. Since free cyanide ions quickly form hexacyanoferrate ions with
the ubiquitous iron ions of the soil, the iron ions are also responsible
for trapping damped cyanides in soils. Goethite is found all over the
planet, usually in the form of concretions, stalactitic formations,
oolites (a form consisting of tiny round grains cemented together),
reniform (kidney shapes) or botryoidal (globular, like bunches of
target chemical Prussian blue is strongly adsorbed to geolite. Goethite
is common component of soil.
