Properties and typical application
|
|
Copper (Cu) is a common source of the environment and an important trace element
for human health. It occurs as a reddish metal with a characteristic cubic
crystalline structure, is highly ductile, malleable and a very good conductor
for heat and electricity.
Due to its excellent process and corrosion properties, copper is used as pure
metal and in alloys.
In a great number of metal processing activities cupric waste comes into
existence that has to treated and cleaned before draining, but copperis
released into the enviroment by natural sources like decaying vegetation and
forest fires, too.
Copper typically is intensely used for electrical and electronical equipment,
but also in the field of construction (roofing and plumbing) and in various
alloys as bronze and brass. Further, copper is an important trace element in
animal feed.

Toxicology
|
|
For copper the guideline value for chemicals that are of health siginificance in drinking
water according to
World Health Organisation
is 2 mg/litre.
Intense and long-term exposure to copper causes, amongst others, irritation of
nose, eyes and mouth, head- and stomachaches. Very high reception of copper can
cause damages to liver and kidney and even cause death.
Copper causes damages of the environment by negatively interrupting activities
of microorganisms and plants, and as a consequence limiting fertility of the soil.

Method
|
|
SEIBOLD Online-Analysers support two different methods of measurement of copper,
using either an ion selective electrode or a colourimetric method.
Low concentrations of copper are measured my means of a colourimetric method,
based on the chemical reaction of cuprizon. The stable blue complex resulting
from adding two (2) reagents to the sample to be measured can then be analysed
by the use of a photometer unit.
For measurement of higher concentrations of copper a combination of an ion
selective electrode and a reference electrode is used. The pH-value of the
sample is to be adjusted and stablised by the use of a buffer solution.

Johann Heinrich Schmelzer
|
|
Viennese composer, violinist and bandleader Johann Heinrich Schmelzer was born
in Scheibbs (A) around 1623 and died around 1680 in Prague. Johann H. Schmelzer
was oneof the most popular violinists of his time and played in the Wiener
Hofkapelle, the royal orchestra. He supported emperor Leopold I with his
compositions and was ennobled by Leopold I. Later in his carreer Johann Heinrich
Schmelzer was bandmaster at the court of the Habsburger.
Prominent work of Johann Heinrich Schmelzer:
"Sacroprofanus Concentus" (1662)
"Sonatae unarum fidium seu a violino solo" (1664)
"Die musikalische Fechtschul" (1668)
