تحضیر کاربون منشط بالمعالجة الکیمیائیة ودراسة تأثیر اشعة کاما علیه

In this work activated carbon of a good quality was prepared using oxidation condensation process, The oxidation of the asphaltic materials was conducted using 2% by weight of FeCb and in the presence of a strea:n of air. The reaction mixture was heated at 350:C for 3hrs, followed by removal of uncarbonized material tinder reduced pressure.The condensed fraction obtained is expected to recombine or re-react to give a high carbon content. The carbonized was conducted at 550±25°C for 3hrs and the ratio of the feedstock to KOH was (1:2), alter the carboni/ation the reaction mixture was subjected to purification by treatment with 10% HCI under reflux .for 1 hr. filtrated and then washed by distilled water till it give neutral test litmus paper. The sample was dried at 120'C for 24hr and its physical properties were determined. Their: the samples (prepared & commercial) were irradiated at room temperature using different times of irradiations. The physical properties for activated carbon were determined in order to know effect of gamma irradiation.الخلاصة یتضمن البحث تحضیر کاربون منشط من المواد القیریة عن طریق اجراء عملیة اکسدة بإستخدام 2% وزناً من کلورید الحدیدیک وإمرار تیار من الهواء عند 350oم لمدة 3 ساعات، یلی ذلک عملیة ازالة للمواد غیر المکربنة عن طریق اجراء عملیة تقطیر فراغی.بعد ذلک یتم تعریض المنوذج التجاری والنموذج المحضر لجرعات مختلفة من اشعة کاما، ویتم قیاس مواصفات هذه النماذج مرة اخرى لمعرفة تأثیر اشعة کاما على فعالیتها.
