Abstract AR
تضمن البحث حساب جهد احتمالية الالتصاق (S*) و طاقة التنشيط الظاهرية(AAE) بعملية الامتزاز لبعض الحوامض العضوية الكربوكسيلية الأروماتية باستعمال رمل (طين) تم تجميعيه من العواصف الترابية القادمة إلى مدينة الموصل كمادة مازه جديدة .
النتائج التي تم الحصول عليها أظهرت حصول امتزاز فيزيائي و هو المفضل و ذلك بتطبيق معادلة ارهينوس المطورة من خلال قيم كل من ( S* ) و ( AAE ) و التي تمتلك قيمة قليلة و تحمل شحنة سالبة، تحدث عملية الامتزاز بميكانيكية تتألف من خطوتين ، و تم دراسة تأثير التركيز و درجة الحرارة فضلا عن تأثير المجاميع المعوضة على الحلقة الأورماتية على طبيعة الارتباط بين أنيونات الحامض الكربوكسيلي العضوي و الأكاسيد الفلزية اللاعضوية لتكوين نموذج معقد السطح و توصلت هذه الدراسة إلى أن قيم (S*) لكل الحوامض هي أقل من الواحد و أكثر من قيمة الصفر كما أن قيم (AAE) أعطت مؤشرا على أن عملية امتزاز باعثة للحرارة و تلقائية أن وجود جزيئات الماء و أيونات (H+) مهم جدا لتغير طبيعة سطح الرمل .
Abstract EN
This study includes calculation of the potential stickiness (S*) and apparent activation energy (AAE) by the adsorption process of some aromatic carboxylic acids using sand (clay) as a new adsorbent material.
This clay was collected from dust storms coming to the city of Mosul.
The obtained results showed that physical adsorption which is achieved by applying the modified Arrhenius equation through the values of (S *) and (AAE) which have low values and bear a negative charge is preferable.
Adsorption process occurs in two-step mechanism.
The effect of the concentration of the acidic solution, temperature and the substituted groups SO3, NO2, OH, NH2 on the aromatic ring) was studied to clarify the nature of the association between organic carboxylic acid anions and inorganic metal oxides to form a complex surface model.
The study concluded that the values of (S *) for all acids were less than one and they were more than the value of zero.
Also, the values of (AAE) gave an indication that the adsorption process is exothermic and spontaneous.
The presence of water molecules and (H+) ions in solution is very important to change the nature of the clay surface.
