Abstract :

In this Paper, Activated Nano-Graphene Hase Been Used As A Sorbent for The Removal of 4-Chloro-2-Nitrophenol From Aqueous Solutions. The Process of Removal Has Been Optimized for Different Parameters Like Initial Concentration Of 4-Chloro-2-Nitrophenol, Contact Time, Ph, Adsorbent Dose, and Temperature. Also, Phzpc Of The Adsorbent Was Determined. Results Showed  That Equilibrium Was Achieved in 20 Min and Removal Of  4-Chloro-2-Nitrophenol Increased By Increasing of Adsorbent Dosage And Temperature . The Experimental Results Indicate That 0.004g/250 Ml of Activated Nano-Graphene Was Able To Remove 97.55%  of 4-Chloro-2-Nitrophenol From An Initial Concentration of 10 Mg L-1 At Ph Of Solution.
