摘要：

The purpose of this study was to show the influence of aluminium ions on the organic matter adsorption. The adsorption was realised onto powdered actived carbon (100 mg.L-1), either in buffer medium or in distilled water. The value of pH was adjusted to 4.6. The results indicate -i) that buffer medium decreased the adsorption of molecules (phenol, tannic and salicylic acids), due to a competition between organics and buffer constituents, and -ii) that aluminium ions could increase the adsorption of some molecules (tannic and salicylic acids) by a complexation phenomenom. Langmuir equation was used to determine adsorption capacities.
