An adsorbent-containing sheet is prepared from a slurry comprising a mixture of fibre, binder, adsorbent and flocculating agent in deionised water. An alkali or alkaline metal salt is added to the slurry. Typically, both the adsorbent and the salt contains lithium cations. In addition, the invention provides for washing an adsorbent-containing sheet with an aqueous solution of the alkali or alkaline metal salt. |
