Abstract AR

في هذه الدراسة تم إزالة مركب البارا نايترو أنلين بوساطة سطح طين البنتونايت كدالة لدرجة الحرارة و التركيز و الدالة الحامضية.

تم تحديد زمن الاتزان لعملية الامتزاز باستخدام تقنية مطيافية امتصاص الأشعة المرئية-فوق البنفسجية ووجد بأنه مساو إلى 65 دقيقة.

و وجد أن كمية الامتزاز تقل مع زيادة درجة الحرارة و الدالة الحامضية، تم تطبيق معادلة (D-R) الايسوثرمية و من خلال هذه المعادلة تم حساب معدل طاقة الامتزاز و ذلك من خلال ثابت طاقة الامتزاز.

تم حساب ثابت سرعة التفاعل لعملية الامتزاز و طاقة التنشيط في الوسط المتعادل.

Abstract EN

In this study, the removal of para nitroaniline (PNA) from aqueous suspension of bentonite was investigated as a function of pH, concentration and temperature.

Adsorption process was attained to the equilibrium within 65 minutes which investigated by using uv-visible spectrophotometer technique.

The adsorbed amount of para nitroaniline (PNA) decreased as the temperature and pH increased.

The Dubinin-Rasdushkevich (D-R) isotherm equation was applied to the data and values of parameters of this isotherm equation was calculated.

The mean energy of adsorption Eads, was also calculated from the adsorption energy constant K/ It’s Value determined from the D-R isotherm equation. The rate constant for adsorption and activation energy value for the adsorpti process was calculated at neutral pH.
