چکیده
|
In this research, the removal efficiency of an acid brown-14 as azo dye was carried out by an adsorbing method using a magnetic-activated carbon adsorbent, through which separation of adsorbent could be performed by a magnet at the end of the process. a second-order reduced polynomial model is used for method and optimization. based on the model foresight, the process can remove the dye up to 82 % under the optimum situations of the primary ph = 4.6, [dye] = 20 ppm, and [ads.] = 791 ppm at room temperature. an experimentally accurate assessment of the model revealed that the model has a good agreement with the model prediction.
