Abstract

In this study, commercial activated carbon and activated carbon/chitosan composites; AC(0.25-0.5), AC(0.5-1), AC/CS(0.25-0.5),AC/CS(0.5-1)mm, were used as an adsorbents to remove methylene blue dye from dilute solution. Three experimental parameters of the adsorption were studied by factorial design . The three factors were, initial concentration of the dye in the solution, presence of chitosan as a coating agent and granular size of the activated carbon. The ANOVA table indicates that the initial concentration of the dye is the most significant adsorption parameter. The maximum value of qt was 7.78mg/g at initial concentration10ppm of the dye. The adsorption data fitted Langumir isotherm .The kinetic study indicate that the adsorption fitted Pseudo-second-order for three adsorbents; AC(0.25-0.5), AC/CS(0.25-0.5), AC/CS(0.5-1).  The results confirm the nature of the adsorption as chimosorption for these adsorbents.

درس امتزاز صباغ أزرق الميتلين على حجمين حبيبين من الفحم الفعال التجاري وعلى خلائطهما مع بوليمير عضوي هو الكيتوزان

AC(0.25-0.5), AC(0.5-1), AC/CS(0.25-0.5),AC/CS(0.5-1)mm

تم تصميم تجربة عاملية لدراسة الظروف الأمثل لامتزاز أزرق الميتلين على المواد المازة المدروسة بأخذ ثلاثة عوامل بالاعتبار هي : التركيز الابتدائي للصباغ في المحلول ، وجود الكيتوزان كعامل تغليف ، الحجم الحبيبي للمادة المازة . بين جدول تحليل التباين ANOVA أن للتركيز الابتدائي للصباغ أكبر تأثير على عملية الامتزاز. كانت أعظم قيمة لتركيز الصباغ في الطور الصلب qt هي 7.78mg/g عند التركيز الابتدائي 10ppm . وافقت بيانات الامتزاز نموذج لانغموير التوازني كما بينت الدراسة الحركية أن امتزاز أزرق الميتلين على AC(0.25-0.5), , AC/CS(0.25-0.5),AC/CS(0.5-1)يتبع نموذج بسيدو من 33المرتبة الثانية وهذا يؤكد أن الامتزاز له طبيعة كيميائية على هذه المواد المازة.
