Properties and typical application
|
|
Chemically active iron (Fe) is a lustrous, malleable and ductile metal with a
greyish tinge and important magnetic properties.
Iron is one of the most common elements on earth (about 5% of the earth´s crust)
and is existent in four distinct crystalline forms. Iron is an essential element
for all forms of life; about 4 grammes of iron is contained by each human
circulating in blood (hemoglobin) in order to transport oxygen.
Iron is extracted from iron ore; it is hardly found in free elemental state,
but typically part of magnetite and hematite (amongst others).
Iron is used for various alloys, first to mention steel. As a consequence of
iron oxidising easily, various methods of improving iron are used in industrial
processes. Most of these processes, as galvanisation or coating, just to
mention a few, are of environmental impact.

Toxicology
|
|
According to the guidlines of the
World Health Organisation,
iron is not of health concern at concentrations normally observed in drinking-water.
Drinking Water Directive (98/83/EC) of the European Union limits the concentration
to not more than 0.2 mg/l iron for potable water.
Ground water may contain iron at a concentration of several milligrams per
litre that causes a red-brown colour of water on exposure to atmosphere, below
0.3 mg/l iron there is no specific taste noticable.
Iron can cause damages to health both in case of deficiency and overdose.
Symptoms for possible deficiency of iron are, amongst others, fatigue and
asthma. High blood pressure, arthritis, heart and liver diseases can be
indicators of iron overdoses.

Method
|
|
The concentration of iron is based on a colourimetric method.
After a reduction to Fe(II) ions in mineral acidic solution, iron ions form a
dark red complex with 1,10-Phenantrolin. The intensity of the resulting colour
is depending on the concentration of iron ions.
The complex coming into existence is very stable and can be evaluated by the
use of a photometer unit.

Joseph von Eybler
|
|
Joseph Leopold Edler von Eybler was born on February,8th 1765 in Wien/Schwechat. He
received first music lessons from his father Leopold, who was a school teacher and
choirmaster. At the age of six, he attended Wiener Stadtseminar and was educated
by Josef Haydn.
Joseph Eybler was not able to finish his studies of jurisprudence and had to work as
private tutor and musician. With support of Josef Haydn he became choirmaster at
Schottenkloster in Vienna in 1794. In 1804 he was promoted deputy bandmaster at the
Royal Court.
In 1806 he married one of Maria Theresia´s valets, Theresia Müller. In 1824 he
followed Antonio Salieri as Royal Bandmaster. Ten years later he was ennobled by
Maria Theresia. Joseph Leopold Edler von Eybler died in 1841 at the age of 81 in
Vienna.
Prominent works by Joseph Eybler:
Two oratorios ("Die Hirten bey der Krippe zu Bethlehem", "Die vier letzten Dinge")
More than 30 masses
A clarinet concerto in B flat major
A string trio
A strong quartett
2 symphonies
