Abstract

This study is using one of many methods that used to remove heavy metal from industrial. They include chemical precipitation, ion exchange, electroplating, and membrane separation. This study of rice husk as potential activated carbon as a lowcost adsorbent to remove Nickel (Ni) from Ni (II) ion solution was investigated. It used adsorption method as it is cheaper than others and readily available. This project will focuses on the capability of the rice husk as a low-cost adsorbent to remove heavy metal. Raw rice husk, is largely available in Malaysia, as our country main agriculture product is rice. Since rice husk is treated as waste, we are studying ofthe potential of its' advantages in removing heavy metal. The main components of rice are carbon and silica. Thus it has potential to be converted as an adsorbent. This study involves 3 steps which are the preparation ofthe raw rice husk, activation stages (treatment ofrice husk and carbonization of the treated rice husk), and the kinetic study for the rice husk obtain after activation in order to obtain Langmuir graph. The pores development will be analyzed by using both SEM and FESEM for each stage. Other analyses on rice husk activated carbon were also conducted using BET Surface Area Analyzer, Fourier Transmitted Infrared Spectroscopy (FTIR), CHN Elemental Analyzer, X-Ray Diffraction (XRD) and Thermo gravimetric Analyzer for characterization study on rice husk particle. The adsorption capacity towards metal ion was determined using Atomic Adsorption Spectroscopy (AAS). The result obtained from the adsorption study showed that rice husk has a potential to be converted to adsorbent for removal ofheavy metals.
