Spectrophotometric Determination of Micro Amount of Copper (II) in Different Enviromental and Vital Samples by New Organic Reagent

الملخص

2-[4-Chloro-2-methoxy phenyl azo]-4,5-diphenyl imidazole used as a new
complexing organic reagent for extraction and determination of copper (II) in
different samples include plants leaves, soil and water from different position in Al-
Najaf governorate as well samples of human serum, cow liver and kidney, vitamins
and spices. All these measurement carried out at the optimum condition for
complexation reaction. Beer's law is obeyed over the concentration rang 0.5-30μg/mL
with a detection limit 8×10-5 μg.mL-1 and molar absorptivity 8459.79L.mole-1.cm-1.
Sandell’s sensitivity 7.5×10-8μg.cm-2.
