Magnetic activated carbon optimization using response surface approach for Cr(VI)

Abstract Magnetic activated carbon (Fe 3 O 4 -AC) is made using Fe and as primary materials to adsorb Cr(VI) in simulated wastewater. The Response Surface Method (RSM) optimizes the experimental parameters (pH, temperature, initial solution concentration, dosage). impacts of various elements are explored determine ideal reaction conditions for maximum elimination. According data, interaction between pH other three exceptionally significant (P<0.0001) response. Furthermore, a removal rate 83.88 percent may be attained at pH=2, temperature 62°C, starting concentration 179mg/L, activate dosage 0.14g/50mL.
