Adsorption of dye yellow no. 6 from synthetic wastewater by activated carbon derived from waste polymer via microwave irradiated

Wastewater containing medical dyes is one among the foremost essential contamination effects of natural aquatic ecosystems. The current study investigates the optimal operating conditions for removal of dye (Yellow No.6 (C16H10N2Na2O7S2)) from synthetic wastewater. Experiments were conducted on activated carbon (AC) prepared from waste polymer through microwave irradiated. Effects of the adsorption parameters (initial dye concentration, amount of adsorbent, and system temperature) on the dyes removal efficiency were study and optimized by response surface methodology (RSM). The optimal operating conditions for dye removal were establish at an initial dye concentration of 30 mg/l, amount of adsorbent of 0.022 g and system temperature of 32°C with an adsorption removal efficiency of 98.72%. The adsorption removal efficiency increased with increasing the dosage of activated carbon from 0.005 to 0.03 g. While the increase in initial dye concentration from 25 to 100 mg/L and system temperature from 25 to 50°C caused decrease in removal efficiency.
