Removal Congo Red Dye on Surface of Nano Charcoal Activated by Used Central Composite Chemometric Method

In this paper; the modern method was used to remove the congo red dye (CR) from its aqueous solutions by chemometric separation. The nano charcoal activated (NCA) was used to remove the CR and the factors affecting the adsorption process were studied simultaneously to reduce the number of experiments followed and to rely on central composite design and the method of response surface by used statistica 12 program. This gives the relationship between all the variables simultaneously. It was found that the removal efficiency reached to 98.371%. (paper)
