Abstract AR
تم - في ها البحث - اختبار قدرة الكربون المنشط على إزالة الملكيت الخضراء في وسط مائي.
و قد قمنا بدراسة العوامل التالية : زمن التعرض، و تركيز الصبغة الأولي، و جرعة الكربون وع امل PH و درجة الحرارة.
و يتبع الادمصاص معادلة من الدرجة الأولى و يتم التحكم بالمعدل بوساطة الانتشار البيني للجسيمات.
و استخدمنا أنموج فريندليش و لانجميور لبيانات الاتزان, فحصلنا على سعة الادمصاص (Qm) من خلال رسومات لانجميور عند درجات حرارة ثابتة و كانت كما يلي : 19.34, 19.76, 20.25, 20.70 (mg/g) عند درجات حرارة : 60°C, 50, 40 30 على الترتيب، و عند عامل PH=6.0.
و أظهر الاختلاف في درجة الحرارة أن امتصاص الملكيت الأخضر ماص للحرارة و فجائي مع نوع من العشوائية على سطح التماس الصلب.
Abstract EN
An activated carbon prepared from Borassus bark, a low-cost source, by sulphuric acid activation, was tested for its ability to remove malachite green in aqueous solution.
The parameters studied included contact time, initial dye concentration, carbon dose, pH, and temperature.
The adsorption followed first order rate equation and the rate was mainly controlled by intra-particle diffusion.
Freundlich and Langmuir isotherm models were applied to the equilibrium data.
The adsorption capacities (Qm) obtained from the Langmuir isotherm plots were 20.70, 20.25, 19.76, and 19.34 mg / g at 30, 40, 50, and 600C, respectively, at an initial pH of 6.0.
The temperature variation study showed that the malachite green adsorption was endothermic and spontaneous with increased randomness at the solid solution interface.
