Potential Use

The potential use of Pleurotus spent mushroom compost as a biosorbent for Fe (II) removal from aqueous solutions was investigated. The experiments were conducted in a fixed-bed column to investigate the influence of various parameters such as flow rate, bed depth and initial concentration on the biosorption of Fe (II). The results of breakthrough time, exhaustion time as well as the Fe (II) uptake and percentage of removal are highly influenced by the flow rate, bed depth and the initial Fe (II) concentration. The results demonstrated that the breakthrough time and exhaustion time increased with decreases in flow rate and initial Fe (II) concentration. Conversely, the breakthrough and exhaustion time decreased as the bed depth decreases.

Eucalyptus Bark

The activated carbon of Eucalyptus globulus was tested for their effectiveness in removing hexavalent chromium from aqueous solution using column experiments. Result revealed that adsorption of chromium(VI) on eucalyptus bark carbon was endothermic in nature. Thermodynamic parameters such as the entropy change, enthalpy change and Gibbs free energy change were found to be 1.39 kJ mol−1 K−1, 1.08 kJ mol−1 and −3.85 kJ mol−1, respectively. Different chromium concentrations were used for the fixed bed adsorption studies. The pre- and post-treated adsorbents were characterized using a FTIR spectroscopic technique. It was concluded that Eucalyptus bark carbon column could be used effectively for removal of hexavalent chromium from aqueous solution at optimal column conditions. This study showed that this biological material is potential adsorbent of Cr(VI) from water.
