Abstract:
Surface of granular activated carbon modified by Fe and Mn is used in the experimental study of dynamic adsorption of 2,4,6-trichlorophenol(TCP) in water. It is showed that the adsorption effect of 2,4,6-trichlorophenol with granular activated carbon modified by Fe and Mn is affected by initial water concentration, initial pH value and flow rate, etc. In addition, to recycle granular activated carbon modified by Fe and Mn, it is oscillated with NaOH solution (mass fraction is 4%) in oscillator at 10 ℃ for 24 h. It is found that the adsorption capability is still good after three times of regeneration.
