Regeneration of Spent Activated Carbon Using Hydrogen Peroxide (H2O2) Agent اعادة تنشيط الكاربون المنشط المستهلك باستخدام بيروكسيد الهيدروجين (H2O2) كعامل مؤكسد

Abstract

A simple , economical process is investigated for regenerating of spent activated carbon , by treatment with hydrogen peroxide solution at room temperature . The regeneration process applied in this work comprises of washing the spent activated carbon by a solution of various concentrations (0.5, 1, 3, 5 %) of hydrogen peroxide, at variable time (30 min - 6 hrs) , the temperature was fixed constant at (25 ºC) . The results showed that a noticeable increase in values of the surface area and pore volume with increasing of hydrogen peroxide concentration (H2O2) and reach a maximum value at (1 %) (H2O2) when surface area (605 m2/g) and pore volume (0.2526 cm3/g) and the perfect time is (3 hrs) .
