Abstract AR
استخدم سطح ماز متوفر ذو كفاءة عالية، غير ضار للبيئة لإزالة الاصباغ والملوثات من مياه الانهار الملوثة صناعيا.
الدراسة تتضمن استخدام قصب البردي من الانهار مباشرة لإزالة الصبغة الزرقاء.
تم دراسة الإزالة بطريقتين، طريقة الامتزاز بواسطة (Batch System) في تراكيز مختلفة، أظهرت النتائج بأن كفاءة الامتزاز تزداد بزيادة التركيز الاولي.
طريقة الامتزاز بواسطة سطح ثايت (Fixed Bed) بحشوة مختلفة الارتفاع (4,204,1.5,1) سم و تراكيز مختلفة (٥، ١٠ و ١٥ مغ / لتر)، تم تطبيق ثلاثة نماذج رياضة لحساب ثوابت الامتزاز هي (the pseudo-first-order, the pseudosecond-order and Elovichmodels).
اثبتت النتائج النظرية أن (pseudo-first-order) ينطبق مع النتائج العملية.
النتائج العملية لطريقة (Batch System) تم تحليلها باستخدام اربع نماذج رياضية هي (Langmuir, Freundlich, Tempkin and Sips equation)، حيث وجد أن النتائج العملية تنطبق على المعادلات المذكورة انفا بصورة جيدة.
تم حساب كفاءة الامتزاز حيث وجد ان معدل الازالة يتراوح بين 90-99 % في وقت 10-20 دقيقة.
أعلى نسبة تم الحصول عليها لإزالة الصبغة عند الاس الهايدروجيني ٨ (8 PH) 100% مع وزن، السطح 1غم ومعدل التدفق 12.5مل / دقيقة بتركيز 15ملغ / لتر في درجة حرارة الغرفة.
Abstract EN
The use of low-cost, locally available, highly efficiencient and eco-friendly adsorbents has beeninvestigated as anideal alternative to the current expensive methods of removing dyes from wastewater.
This study investigates the potentialuse of Can Papyrusfrom river for the removal of methylene blue (MB) dye from simulatedwastewater.
The adsorption of (MB) cationic dye by Can Papyrus was firstly studied in a batchsystem at various dye concentrations.
The results showed that the adsorption capacity ofthe dye increased by initial dye concentration.
Laboratory column experiments were conducted to evaluate the performance of Can Papyrus for MB sorption under dynamic flow using continuous-flow column operation by varying the bed height (1, 1.5, 2.4 and 4cm) and the feed concentrations (5, 10 and 15mg / l).
Three kinetic models (the pseudo-first-order, the pseudosecond-order and Elovichmodels) were used to calculate the adsorption rateconstants.
The adsorption kinetics of the basic dye followedpseudo-first-order model.
The experimental data isothermswere analyzed using the Langmuir, Freundlich, Tempkin and Sips equations.
The adsorption was arapid with 90-99 % of the dye removed within the first 10-20 min.
The adsorption of MB followed the pseudo-first-order rate equation and fits the Langmuir, Freundlich, Tempkin and Sips equations well.
Themaximum removal of MB was obtained at pH 8 as 100 % for adsorbent dose of 1g and flow of 12.5ml / min in concentration of 15ppm at room temperature.
