Title: EXTRACTED LIGNOCELLULOSIC MATERIAL AS AN ADSORBENT AND USES THEREOF
Abstract:
According to an example aspect of the present invention, there is provided a method of removing dissolved contaminants from an aqueous liquid. The aqueous liquid is contacted with an adsorbent which comprises a finely divided lignocellulosic material, which has been subjected to extraction to remove hemicellulose and/or other components therefrom, to bind at least a portion of the organic compounds to the adsorbent. Furthermore, the invention relates to a method for removing or separating dissolved contaminants from a liquid and to a method for producing a liquid containing hemicellulose and/or an adsorbent containing lignin and/or other components. In particular the invention concerns the use of an adsorbent lignocellulosic material for removing dissolved contaminants from a liquid.
