The Hydrophobization of Active Carbons
Three methods for the hydrophobization of active carbons (ACs) have been investigated, i.e. chemical modification, heat treatment under the influence of a ultrahigh frequency electromagnetic field and heat treatment under the influence of a low-frequency electromagnetic field. It is shown that metho...

| description | Three methods for the hydrophobization of active carbons (ACs) have been investigated, i.e. chemical modification, heat treatment under the influence of a ultrahigh frequency electromagnetic field and heat treatment under the influence of a low-frequency electromagnetic field. It is shown that methods involving physical modification are more preferable with the adsorbability of water on the treated AC over the relative pressure range 0.3 to 0.5 being decreased relative to the initial AC. |
