Abstract AR
درس استعمال استخدام طين البنتونايت النانوي كطين محور لإزالة الصبغة الخضراء اللماعة من محاليلها المائية.
و استخدم مجهر القوة الذرية لغرض الحصول على شكل المسام و توزيعه، و تبين أن معدل قطر المسام للطين المحور هو 346.81.
و أجریت وجبات من تجارب الامتزاز على سطح الطين المحور لإزالة الصبغة من محاليلها المائية.
و تبين إن الامتزاز يتبع متساوي درجة الحرارة لكل من لنكماير و فرندلش، و اوجدت قيم الثوابت لكل منهما.
و أمكن حساب قيم الدوال الثرموديناميكية مثل الطاقة الحرة، و الانتروبي، و الانثالبي.
و أوجد ثابت السرعة لعملية الامتزاز باستخدام معادلة لكركرين و تبين أن عملية الامتزاز تتبع حركية المرتبة الأولى فضلا عن ذلك تم تعيين طاقة التنشيط لعملية الامتزاز.
Abstract EN
Application of a Fe-bentonite nano clay (Fe-BNC) as modified clay has been investigated for the removal of birlliant green (BG) from aqueous solutions.
Atomic force microscope measurements give a detailed information on pore shape and pore size distribution about the clay.
These measurements show that the average diameter of the improved clay is 346.84 nm.
Batch adsorption experiments were carried out for the removal of (BG) from aqueous solutions onto Fe-BNC.
Equilibrium data were fitted to Freundlich and Langmuir isotherm equations and the isotherm constants were determined.
Thermodynamic parameters such as free energy, entropy and enthalpy, have been calculated For the modified clay the study of adsorption rate constants has been carried out using lagergrens first order rate equations for the adsorption processes and it is found to follow first order rate kinetics.
In addition, an activation energy of sorption has also been determined.
