Copper is a heavy metal extensively examined in environmental,
industrial and biological applications. Copper is vital and toxic for
many biological systems [1,2], so that its determination in water
samples is warranted by the narrow window of concentration
between essentiality and toxicity [3,4]. On the other hand, copper
is an important element in geochemistry. It can be easily released
from silicates, sulfites and oxides after some physical and chemical
weathering and then transferred by water into soil and sediments
[5]. Thus, the determination of trace amounts of copper in different
matrices is of great importance
