There are some problems in the traditional Fenton process

such as narrower range of pH

and the difficulties to recovery Fe3+ and to reuse it.Based on the design idea of "immobilizing active ions and localizing acidic environment"

Fe/AC catalysts were prepared by acidifying surface of activated carbon and then loading Fe3+ on the modified AC

to study the relationship between Fe/AC catalyst performance and preparation parameters.The results show that Fe/AC catalyst with higher activity and stability are prepared at the conditions of Fe3+loading amount 44.05 mg·g-1 and calcination temperature 200℃.The degradation of bisphenol A(BPA)

an environmental hormone(endocrine-disrupting chemical)

was conducted using the Fe/AC catalyst prepared at these optimum conditions

and the results show that the optimal conditions for degradation of BPA are as follows:reaction time 60 min

temperature 20℃

pH 4.0 to 8.0

Fe3+/H2O2 molar ratio 0.007—0.012

and 30% H2O2 dosage 0.04 ml·(mg BPA)-1.The Fe/AC catalyst prepared exhibits excellent performance for reutilization

showing greater prospect for application in treating wastewater.
