Abstract

A new and novel adsorbent was obtained byimpregnation ofMoringa oleiferaleaf in H2SO4andNaOH, respectively. Prepared adsorbents were character-ized using elemental analysis, FT-IR, SEM, TGA and EDXanalyses, respectively. The effects of operational parame-ters, such as pH, moisture content, ash content, porosityand iodine number on these adsorbents were investigatedand compared with those of commercial activated carbon(CAC). EDX results of acid activatedM. oleiferaleaf havethe highest percentage of carbon by weight (69.40 %) and(76.11 %) by atom, respectively. Proximate analysisshowed that the fixed carbon content of acid activatedM.oleiferaleaf (69.14±0.01) was the highest of all adsor-bents studied. Conclusively, the present investigationshows that acid activatedM. oleiferaleaf is a good alter-native adsorbent that could be used in lieu of CAC forrecovery of dyes and heavy metal from aqueous solutionsand other separation techniques
