In this paper; a modern method was used to remove the Gentian violet dye (GV) from its aqueous solutions by chemometric separation. The Nano charcoal activated (NCA) was used to remove the GV, and the factors affecting the adsorption process were studied simultaneously to reduce the number of experiments followed and to rely on a central composite design which type CCD and the method of response surface by used STATISTICA 12 program. That gives the relationship between all the variables simultaneously. It was found that, the optimum removal efficiency reached 98.042% and it was obtained under the following conditions; The initial concentration of (GV) 12.086 mg/L, Amount of Nano charcoal activated 0.371 g, pH 7.567, Shaking time 22.934 min, and Temperature 312.092 K.
