(EP909212-A1)      New adsorbent composition comprises a modified carbonaceous material with 1 organic group attached to the carbonaceous material.    Also claimed are (i) a method for increasing the adsorption capacity of a carbonaceous material by attaching 1 organic group capable of increasing adsorption, (ii) a method for adsorbing an adsorbate using this material and (iii) an ion exchange material comprising the adsorbent composition containing an organic group with an exchangeable ion.    USE -   The adsorbent is used to remove polar (especially water) and non-polar adsorbates from the gas, vapour or liquid phase. It is also used in separations ranging from water treatment to metals separation/recovery, ion exchange and catalysis etc.    ADVANTAGE -   The adsorbent surface can be extensively modified without damaging its structure or making it more friable. The organic group can be chosen to selectively increase or decrease adsorption affinity of one component of a mixture to maximise its separation. Compared to conventional polymeric ion exchangers, the adsorbent has higher temperature stability, greater resistance to swelling and greater mechanical strength without an adverse effect on uptake kinetics.
