The adsorbent comprises activated carbon bound with a binder material consisting essentially of a water permeable organic polymer from the group cellulose nitrate, a cellulose ester and/or a mixture thereof. Another aspect of the invention is a method of manufacturing the adsorbent comprising (a) mixing together a powder of activated carbon, a powder of binder and a liquid organic solvent to form a malleable mixture; (b) forming the malleable mixture into discrete formations; (c) removing the solvent from the formations to obtain hard dry formations; and (d) breaking the hard dry formations into particles of desired sizes. |
