Abstract AR
يهدف البحث إلى إجراء المقارنة لفاعلية موديلين رياضيين هما موديل Dubinin-Redushkevich و موديل Temkin لوصف عملية امتزاز الزئبق ضمن المحلول المائي باستخدام الكاربون المنشط.
و قد تم اجراء التجارب المتقطعة في درجة حرارة 30○ و قيمة (pH=7) و قد وجد أن معامل التصحيح (R2) للموديل الرياضي الأول يساوي (0.9928) بينما كانت القيمة للموديل الثاني تساوي (0.942) كذلك تم تطبيق معيار (HYBRID) الانحرافي للخطأ و وجد أن قيمته للموديل الأول يساوي (0.0128) بينما للموديل الثاني (0.129).
Abstract EN
Activated carbon has been used as an adsorbent in this work to remove mercury from aqueous solutions.
The aim of the work is to test how best activated carbon can be used as an adsorbent for mercury.
Equilibrium isotherms, both, Dubinin-Redushkevich, and Temkin have been test.
The batch experiments were conducted at room temperature (30oC) and at the normal pH (7.0 ± 0.1) of the solution.
HYBRID fraction error function analysis shows that the best-fit for the adsorption equilibrium data is represented by (D-R) model rather than Temkin model.
Its found that the correction factor (R2) for (D-R) is 0.9928 while for Temkin model is 0.942, also the HYBRID fractional error was conducted for the both models and (D-R) model give minimum value of (0.0128) while it was (0.129) for Temkin.
