- W201877480 abstract "Gelam wood (Meleuca Cajiputi) was used as a precusor for thepreparation of activated carbon. Potassium orthophosphate, potassium hydroxide ,phosphoric acid and carbon-dioxide were used as chemical and physicalactivating agents. The industrial activated carbons AC (7080 and 4050) were usedas comparison. In addition physically activated carbon of rice husk was alsoused in this study. Thirty grams of shredded gelam wood were impregnatedwith 9% w/w K3P04, for the potassium hydroxide impregnation 9% w/w KOHwas impregnated with thirty grams of wood. 2. 2 M H 3P04 concentration ofphosphoric acid was used for the impregnation of thirty grams of gelamwood.Then the impregnated wood was carbonized in a horizontal electricfurnace. The activated carbons were washed using 1.0 M nitric acid followed bydistilled water using reflux method.Surface area, functional group analysis, elemental analysis, pH effect, moistureand ash content are some of the characterization methods done on theactivated carbons. The study of the surface morphology was done using thescanning electron microscope. Elemental constituents of the activated carbonswas done using atomic absorption analysis. The atomic absorption spectrashowed that Ca, K, Mg, Zn, Pb and Fe were present m the activated carbons." @default.
