可以明显看出，在同等实验条件下SG-APT-DDF在混合染料组分模拟废

It can be clearly seen that under the same experimental conditions, the decolorization effect of SG-APT-DDF in the simulated wastewater of mixed dye components is worse than that of single dye component simulated wastewater, which may be related to the interaction between dye molecules. <br>When the adsorbent was just added, the mutual repulsive force between the particles decreased, so that the particles began to coagulate. When the dosage was increased to 0.3g/L, the repulsive force between the particles was the smallest, and many adsorption sites were exposed at the same time, and the decolorization effect was the best. When the dosage of adsorbent is continuously increased, the particles in the solution are surrounded by the adsorbent, and it is difficult to contact with other particles, and the repulsive force between them increases, resulting in little change in the decolorization effect of flocculation capacity.
