Abstract AR
تم اقتراح طريقة طيفية و بسيطة و حساسة و سريعة لقياس كمية ضئيلة من النحاس (II).
تعتمد الطريقة على تكوين مركب 1: 2 مع 3- (3-phenylpyrazylazo) 2، 7-naphthalendiol (3PPAN) عند تطوير كاشف جديد.
يحتوي المجمع على أقصى امتصاص عند 516 نانومتر و (ε أقصى) 9.5 × 10 3 لتر.

تم اختبار دقة و استنساخ طريقة تحديد كميات مختلفة معروفة من النحاس (II).
النتائج التي تم الحصول عليها دقيقة (RSD كانت 0.206 ٪) و دقيقة (كان الخطأ النسبي 1.14 ٪).

Abstract EN
A new, simple, sensitive and rapid spectrophotometric method is proposed for the determination of trace amount of Copper (II).
The method is based on the formation of a 1: 2 complex with 3-(3-phenylpyrazylazo)2, 7-naphthalendiol (3PPAN) as a new reagent is developed.
The complex has a maximum orption at 516 nm and (ε max ) of 9.5x10 3L.

A linear correlation (1.25 –10.

ml-1) was found between orbance at λ max and concentration.
The accuracy and reproducibility of the determination method for various known amounts of Copper (II) were tested.
The results obtained are both precise (RSD was 0.206% ) and accurate (relative error was 1.14 % ).
The stability constant of the product was 5.00X10 10 L.

The method was applied successfully in green cabbage leaves.
