rice hull ash; pellet adsorbent; surface modification
Rice hull ash (RHA) of large surface area was obtained by acid wash and then calcination at 600 degreesC for 4 h. The white ash was then mixed with kaolin and starch ro make pellet adsorbents with reasonable strength to be utilized in a packed column. Both ash and pellet samples showed good adsorption capacities toward the organic substances in wastewater. Furthermore, the surface nature of the white ash and pellet adsorbent could be modified through either hydration or esterification reactions. Corresponding changes in silanol concentrations were successfully correlated to changes in adsorption capacity toward either Congo red or vacuum pump oil molecules. (C) 2001 Elsevier Science Ltd.
