: Activated carbon has been there with us for centuries. It has wide applications in various industries, water-treatment,
dye, sugar refining among others. Water pollution is one of the pressing environmental issue facing Nigeria. The production of
activated carbons locally and from locally available materials would be one of the most lucrative and environment-friendly
solutions to this as it would transform negative–valued wastes to valuable materials. Thus, the main objective of this research
was to prepare activated carbons from rice husk using a chemical activation method with phosphoric acid as an activating agent
and to determine its efficiency in water treatment.
