تقدير الفينول الممتز على سطح الكاربون المنشط المحضر من قشور الرز العراقي بمنظومة حقن جرياني مصنعة محليا

Abstract

pre-preparation of rice husk and determination of optimum temperature of formation activated carbon from them , that found 400 .phenol adsorption have been done on this surface . The contact time , pH , dose of adsorbent and initial concentration of phenol were studied . The contact time was 30min and pH was 3. The increasing of adsorbent dose increasing the adsorption ability and the increasing of initial phenol concentration lead to increasing in adsorption capacity . The adsorption capacity was 0.676 mg/g for 10 ppm of phenol concentration . The adsorption phenol on this surface obey Frendlich and Langmuire isotherms
