Abstract

In this work, pomegrante peel (PGP) was investigated as adsorbent for removal of nickel ions from aqueous solution. It was found that maximum adsorption occur at PH7. Their equilibrium data were fitted with the Freundich and Langmuir isotherms. The adsorption kinetics data were best fitted with the pseudo–second order

في هذا البحث تم استخدام قشور الرمان كماده امتزاز لازاله ايونات النيكل (II) من محاليل المائيه، ولقد وجد ان أفضل امتزاز يحصل عندpH7) ). قيم التوازن الحراري تتفق مع معادلات فريندلش ولاينكماير، حيث ان دراسه حركيه الامتزاز تتفق مع مرتبه التفاعل الثانيه الكاذبه.
