The results showed that CMCS appeared a good adsorbent for Fe 2+ in solution with pH 6~8 and the adsorption capacity of CMCS increased with the increase in its carboxyl groups. The adsorption isotherm of CMCS for Fe 2+ at 20 ℃ was fitted good for the Langmuir equation.展开更多
文摘The adsorption isotherm and adsorption reaction kinetics of carboxymethyl chitosan(CMCS) for Fe 2+ have been studied. The results showed that CMCS appeared a good adsorbent for Fe 2+ in solution with pH 6~8 and the adsorption capacity of CMCS increased with the increase in its carboxyl groups. The adsorption isotherm of CMCS for Fe 2+ at 20 ℃ was fitted good for the Langmuir equation.
