Programming Adsorptive Removal of Organic Azo Dye from Aqueous Media Using Magnetic Carbon Nano-Composite

In this research, the removal efficiency of an Acid Brown-۱۴ 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 ۸۲ % under the optimum situations of the primary pH = ۴.۶, [Dye] = ۲۰ ppm, and [Ads.] = ۷۹۱ ppm at room temperature. An experimentally accurate assessment of the model revealed that the model has a good agreement with the model prediction.
