الخلاصة (( Abstract

اشتمل البحث على دراسة لعدد من العوامل المؤثرة على عملية التلبيد الكهربائي مثل(‏ تركيز الصبغة، تركيز الألكتروليت ونوع القطب المستخدم في العملية . تم تطبيق البيانات باستخدام خلية زجاجية مصنوعة بالابعاد الطول(10cm) العرض (8cm) الارتفاع (6cm) بسعة 300ml مليلتر بإستخدام قطب الستانلس ستيل(SS316) كل واحد منها بأبعاد الطول(8) العرض (7cm) سم السمك(0.1cm) ربطت بمسافة بين الاقطاب (4cm) وتوصيلها إلى مصدر طاقة كهربائي وبجهود مختلفة (5,10,15,20,25V) و بمدى من التراكيز (100,200,300,400ppm) للصبغة المذكورة آنفاً وبإستخدام الملح (Na2SO4) كالكتر وليت وبتراكيز (50,100,150ppm) عند درجة حرارة المختبر. تشير النسبة المئوية للإزالة (R%) على أنها تزداد مع زيادة كل من الزمن ونقصان تركبز الالكتروليت ونقصان تركيز الصبغة عند استخدام قطب الستانلس ستيل(SS316) . اتضح من الدراسة ان افضل نسبة إزالة تحققت عند تركيز (100ppm) عند قطب الستانلس ستيل حققت بنسبة (88%) و بتركيز الكتروليت (50ppmm) اشارت النتائج ان النسبة المئوية للإزالة للصبغة المدروسة تزداد وحسب الترتيب التالي: تمت دراسة حركية الإزالة للصبغة وبتركيز (200ppm) مع وجود الالكتروليت ومن خلال تطبيق معادلة المرتبة الأولى حيث اعطت قوة علاقة جيدة جداً دليل على سلوك العملية المرتبة الأولى الوهمية الكاذبة وتم حساب قيم ثابت السرعة k‏.

ومن ثم تم حساب قيم (H△) و(G△)و(S△) ومن خلال قيمة (H△) السالبة دلالة على ان التفاعل باعث للحرارة, وقيمة (G△) الموجبة الدلالة على ان العملية تلقائية ومن خلال قيمة (S△) الموجبة دلالة على وجود حالة نهائية اكثر من عشوائية وذلك بسبب وجود اكثر من طور في المحلول.

الكلمات المفتاحية: التخثير الكهربائي, قطب الستانلس ستيل, صبغة ليشمان.
