ln the first part of the thesis, the capability of activated carbon fiber (ACF) treated bydifferent kinds of acids for adsorption removal of thiophenic sulfur compounds was evaluatedin the batch-type adsorption process. The results show that the as-received ACF adsorbent,efficiently adsorbs the bigger size sulfur compounds, and the removal efficiency for the

Effect of treatmenttemperature and time by SN acid (ratio of volume of H,SO4 to HNO, is 3:1) on ACFadsorption removal of thiophenic sulfur compounds was studied.The results show thatoxidation with SN acid at room temperature can remove the ashes or inorganic components ofthe ACF adsorbent as well as change in the surface

, the adsorption capacity can be calculated according to the following formula
cn.cDm
The size of Q in addition to the variety of activated carbon, but also with the nature of the adsorbed substance, concentration, water temperature and pH value.
Generally speaking, when the adsorbed material can react with the activated carbon, the adsorbed material is not easy to dissolve in water and is repulsed by water, and the activated carbon on the adsorbed material affinity force is strong, the concentration of the adsorbed material is larger, Q.
The value is larger.
