Optimization of Sibipiruna activated carbon preparation by simplex-centroid mixture design for simultaneous adsorption of rhodamine B and metformin.

The present paper reports the application of augmented simplex-centroid mixture design to obtain a high BET surface area activated carbon using as reactants KOH, KCO and KCO. The optimum mixture composition was 2.51 g of KOH, 0.

Stevia residue as new precursor of CO-activated carbon: Optimization of preparation condition and adsorption study of triclosan.

The present work reports the preparation of CO-activated carbon (AC) using Stevia rebaudiana (Bertoni) residue as a new carbon precursor. The experimental parameters were optimized via chemometrics tools to obtain an AC with high BET surface area (S). The found optimum condition was: activation temperature of 900 °C, CO flow of 165 cm g and activation time of 60 min, providing an AC with S of 874 m g.
