Adsorption Effect for Aromatic Chlorocompounds on the Granular Activated Carbon |
| Abstract |
The adsorption effects of aromatic chlorocompounds on Granular Activated Carbon were studied in the pH range from 3 to 10. At pH4 the adsorption ability of Granular Activated Carbon for chlorobenzene was most effective among the tested compounds. The comparative value surface diffusiving and pore diffusiving of aromatic chlorocompounds determined by HMN method were Ds/Dp $lt;0.02421 such consequently surface diffusion rate was greater than pore diffusion rate on fact was found control by surface diffusion and also surface diffusivity is the most important design variable. The amount of adsorption on chlorobenzene were 68㎎/g, this change can be tendency on increase concentration and show consider freundlich isotherm equation. The break time and breakthrough curves by constant pattern linear driving force model (cp-LDF model) showed good agreements with the experimental break time (Variation less than 8%) and breakthrough curves. |
