Adsorption of dyes from aqueous solution — the effect of adsorbent pore size distribution and dye aggregation

摘要: The removal of acid dyes, Tectilon Blue 4R, Red 2B and Orange 3G, from single component solution by adsorption on activated carbon bone char has been investigated in isotherm experiments. Results these experiments were successfully modelled using Langmuir Freundlich analyses. Nitrogen analysis was also undertaken indicated that the had a much higher specific surface than char. Calculations involving pore size distribution data indicate only 14% total is available for due to high molecular area aggregation dye. equilibrium dye takes place solid phase both adsorbents with numbers found char, which indicative multilayer adsorption.
