Abstract AR
2كلورو-2ميثوكسي فنيل ازو]-4,5 -ثنائي فنيل اميدازول استخدم ككاشف تعقيد عضوي جديد في نماذج مختلفة تضمنت أوراق النباتات، التربة، المياه من مناطق مختلفة (II) لاستخلاص و تقدير النحاس في محافظة النجف الأشرف و كذلك نماذج مصل دم الإنسان، كبد و كلية البقر فضلا عن بعض الفيتامينات و التوابل.
و كل هذه القياسات تمت تحت الظروف المثلى لتفاعل التعقيد.
المطاوعة لقانون بير كانت في حدود 8 و قيمة الامتصاصية المولية × 10-5 μg.mL- 0.5-30 و كان حد الكشف 1 μg /mL التراكيز حساسية ساندل7.5 × 10-8μg.cm- 8459.79 L.mole-1.cm- .
Abstract EN
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 0.5-30 μg / 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.
