Abstract

This study investigated the adsorption potential of corncob-based activated carbon to remove toxic material from industrial waste. In this project, the activated carbon was prepared and some testing has been done to study the characteristics of the activated carbon produced. The experimental work can be divided into three main parts which are sample preparation, sample characterization and sample testing. Sample preparation is the process where we convert the raw material to activated carbon. Sample characterization is done to study the characteristics and physical properties of the activated carbon. Meanwhile, sample testing was conducted to see the adsorption potential in term of adsorption capacity. Carbon Hydrogen Nitrogen Sulphur (CHNS) Analyzer and Scanning Electron Miscroscope (SEM) were used to study the characterization of produce activated carbon. For SEM testing, another sample was created without chemical agent. The purpose is to see the effect of chemical agent towards surface area and porosity of the activated carbon. The author also had used American Standard Testing Method (ASTM) to study the characterization of raw material. For adsorption testing, Gas Chromatography (GC) has been used. It was observed that the carbon content for production of activated carbon from corncob was 53.32% meanwhile by during ASTM Method it was 38.07%. It is also shows that activated carbon with chemical agent gives a better surface area and porosity development. Lastly, maximum adsorption of 12.03% was observed with the corncob activated with potassium hydroxide (KOH) at 700ºC.
