Biosorption of phenol from aqueous solution by biosolids.
Studies on the removal of phenol from aqueous solutions by adsorption on sewage treatment plant biosolids (BS) as low-cost adsorbent were carried out with an aim to obtain information on treating phenol-containing wastewater from different industries. A series of experiments were undertaken in a batch adsorption technique to access the effect of the process variables i.e. initial phenol concentration, contact time, initial pH and adsorbent dose. The results showed that the adsorption capacity of BS in aqueous solution increased with the decrease in initial concentration and pH, and increase in contact time and dose of adsorbent. The experimental results were fitted by Langmuir and Freundlich isotherms to describe the biosorption processes.
