Abstract AR
درس في هذا البحث كفاءة أكسيد الزنك في الأكسدة الضوئية المحفزة لصبغة برومو فينول الأزرق، حيث تضمن دراسة تأثير بعض المتغيرات مثل تركيز العامل المحفز و تركيز الصبغة و زمن التشعيع و الدالة الحامضية على سرعة تكسير (تحطيم) محلول الصبغة.
بالإضافة إلى ذلك فان مظهر (طيف) صبغة برومو فينول الأزرق درست باستخدام تقنية مطيافية الأشعة فوق البنفسجية-المرئية.
أن الامتزاز يتطلب وجود اوكسيد الفلز كوسيط لتكسير الضوئي / إزالة اللون الضوئية، كما أن شمولية إزالة اللون نوقشت وفقا لنموذج لانكمير-هينشلوود.
Abstract EN
In this research, the efficiency of ZnO by photocatalytic degradation of bromophenolblue dye was studied.
Effects of some parameters such as, catalyst concentration ,dye concentration , irradiation time ,and pH on the degradation rate of dye solution were also examined.
In addition, the feature of bromophenolblue dye was studied by using UV-Vis spectroscopy techniques.
Adsorption is a prerequisite for the metal oxide-mediated photodegradation/photodecolorization and the extent of decolorization has been discussed in terms of the Langmuir-Hinshelwood model.
