Properties and typical application
|
|
Nickel (Ni) is a silvery-white metal, showing properties of both ferrous and
nonferrous metals. Nickel is hard, malleable and ductile and is a good
conductor of electricity and heat, but is not found as native metal in nature.
Nickel is primarily used for the production of austenitic stainless steel and
other alloys, characterising strength, ductility, as well as resistance to
corrosion and heat.
Further nickel is used in electroplating solutions, in the production of
catalysts, motor oil, lubricant additives and in various processes of the
chemical industry.

Toxicology
|
|
For nickel the guideline value for chemicals that are of health siginificance
in drinking water according to
World Health Organisation
is 0.02 milligramms/litre.
In general water is only a minor contributor to nickel reception, that is
primarily a consequence of concentrations of nickel contained in food.
The most common way of exposure to nickel and its salts is inhalation.
According to several studies inhaled nickel compounds are possibly carcinogenic.
People long-term exposed to high concentrations of nickel and its salts face
a high risk of development of lung cancer or nose cancer.
People sensitive to nickel may react with typical skin effects ("nickel itch")
even caused by minor quantities of nickel, as for example contained in various
kinds of jewellery.

Method
|
|
Measurement of concentrations of nickel in liquids is based on a colourimetric
method.
A specific nickel reagent is added to the sample. The chemical reaction of
nickel ions with pyridylazoresorcinol (PAR) forms a red complex. The intensity
of the resulting colour is depending on the concentration of nicktl ions in
the sample and is measured by the use of a photometer unit.

Johann J. Fux
|
|
Johann Joseph Fux was born to a peasant family in 1660 in Hirtenfeld in Styria.
Relatively little is known about his early life, but by the 1690s he was in
Vienna, and attracted the attention of Emperor Leopold I with some masses he
composed. The emperor was sufficiently impressed by them to assist him with
his career after this point. In 1698, Leopold hired him as court composer.
Fux served Leopold I until his death, and two more Habsburg emperors after
that. He was famous as a composer throughout this period, his fame being
eclipsed only later in the 18th century as the Baroque style passed away.
Johann Joseph Fux died in 1741 in Vienna.
