摘要：

The adsorption of mercury(II) from aqueous solutions on green tea leaves, coffee beans and activated carbons has been studied comparatively. The adsorption capacity of those adsorbents was little affected by pH and EDTA. The coffee beans and the activated carbons adsorption capacity were highly affected by chloride ion, whilst the green tea leaves were less affected. The adsorption data obtained from equilibrium experiments were well-fitted to Freundlich isotherms.
