لون النحاس (5 × 10 مل) 50 ت

Colorimetric test without deproteinization of the sample. End point increase.
At pH 4.70, in a buffered media, Cooper is released from ceruloplasmine
complex and forms with the specific complexant 3-5 Di Br-PAESA a stable
coloured complex.
The color intensity is proportional to the amount of Cooper present in the
sample.
