ABSRACT - [ Total Page(s): 1 ]The purpose of this work was to study the effect of chemical surface properties of activated carbons for their use in water purification. To achieve this objective, activated carbon in both granular and powdered forms namely: as received and devolatilized carbons were prepared. Proximate analysis of the carbon materials was performed. Mass titration experiments were carried out to determine the point of zero charge of the activated carbon materials. Again, using an ultraviolet spectrophotometer, the adsorption of phenol on as-received and devolatilized activated carbon was investigated. Adsorp

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 ORIGIN AND NATURE OF ACTIVATED CARBONCarbon is the fifteenth most abundant element in the earth’s crust and the fourth most abundant element in the universe by mass after hydrogen, helium and oxygen. Scientists, industries, and consumers use different forms of carbon and carbon containing compounds in many ways such as activated carbon or carbon in its active form which can be used to purify water, among others.Activated carbon is a form of carbon that has been produced to make it extremely porous and thus have a very large surface area available for adsorptio ...
