Optimization of process variables to prepare activated carbon from Noug (Guizotia abyssinica cass.) stalk using response surface methodology.

ABSTRACT: Even though adsorption is considered the simple, effective, and efficient method for the treatment of wastewater, accessibility of low-cost and locally available activated carbon remains the challenge. In response to this, recently significant amounts of agricultural byproducts have been investigated to prepare low-cost porous carbon, but there is still a problem related to cost and availability. So, Noug stalk, chosen because of its abundance and low cost as an agricultural byproduct in Ethiopia, was chemically activated with phosphoric acid to produce a low-cost porous carbon. The production of Noug stalk activated carbon (NSAC) is optimized using response surface methodology. A central composite design was used to investigate the effect of three process parameters, namely carbonization
