Composite adsorbent material

A composite adsorbent material comprises a porous carbon carrier matrix and an adsorbent species which is precipitated within the pores of the carrier matrix. The adsorbent species may be capable of influencing the ionic composition of the surrounding aqueous phase and the resultant composite materi...

Beschreibung
Zusammenfassung:	A composite adsorbent material comprises a porous carbon carrier matrix and an adsorbent species which is precipitated within the pores of the carrier matrix. The adsorbent species may be capable of influencing the ionic composition of the surrounding aqueous phase and the resultant composite material produces an internal chemical environment which is different to that outside the material. The concentration of the carrier matrix in the carrier material may be between 10-99% (w/w) of the total weight of the carrier material. The carrier matrix may comprise, or be derived from a cellulosic precursor material, preferably a lignocellulosic material. The carrier material may be substantially macroporous and have pores in the range of 50-500 nm. The adsorbent species may be basic.
