Abstract AR
تم في هذه الدراسة اختبار قابلية سطوح جسيمات الألومينا المطعمة بمونمر حامض الأكريلك و الألومينا المطعمة ببولي (حامض الأكريلك) لامتزاز جزيئات الفينول و بارا - كلوروفينول تحت ظروف مختلفة من درجات الحرارة. و تم حساب الدوال الثرموديناميكية (ΔH, ΔS, ΔG) لعملية امتزاز الفينول و البارا - كلوروفينول على السطوح قيد الدراسة و أظهرت النتائج قيم موجبة و أخرى سالبة دلالة عمليات امتزاز محبة للحرارة و أخرى باعثة للحرارة.
Abstract EN
The ability of different alumina-grafted particles was examined for adsorption of phenol and p-chlorophenol under different conditions (i.e.
concentrations and temperatures).
Dispersion stability of alumina in liquid medium (water) was studied using settling under gravity technique.
The result shows the settling initial rate of the alumina-grafted acrylic acid particles was faster than initial rate of settling when alumina-graft acrylic acid monomer adsorbed phenol and p-chlorophenol and vice versa to the alumina-graft poly(acrylic acid) polymer.
Thermodynamic parameters values (ΔG, ΔS, ΔH) were calculated for adsorption processes of phenol and p-chlorophenol adsorbed onto different surfaces.
The results revealed that positive and negative values were obtained implying that both endothermic and exothermic adsorption reactions may took place.
