Application of central composite design for preparation of kenaf fiber based activated carbon for adsorption of manganese (II) ion

The objective of this research is to define optimum operating conditions for preparation of activated carbon from kenaf fiber which would conciliate for highest removal efficiency of manganese (II) ions along with maximum possible yield. Kenaf fiber (KF) is used to prepare activated carbon by using...
