It is shown that the AG1 adsorption is at its maximum in the pH 2. In this range of ,acid, pH, the positive charge of the surface of the activated carbon increases, this causes an increase of the electrostatic attraction between the dye and the surface of the adsorbent. The adsorbed amount decreases when the pH increases by 4 to 11.
