The present work examines the possible use of fly ash, a byproduct of coal power stations, as a means of removing phenol from water, or equivalently, of restricting its movement in solid wastes or soil. Equilibrium experiments were performed to evaluate the removal efficiency of fly ash. The adsorption experiments were undertaken using fly ash treated at three different pH levels and with three different temperatures. The results indicate that although phenol can be removed from water, this depends markedly on the temperature and pH value of the treatment solution employed.

Optimized Conditions

Zeolite membranes were successfully synthesized from coal fly ash by hydrothermal treatment onto 10-cm-long tubular porous supports. The membranes were characterized from XRD analysis, SEM observation and the pervaporation performance. Under the optimized conditions, LTA-type membrane from coal fly ash showed fairly efficient for the dehydration of organic liquids. The maximum selectivity reached more than 3000 with accompanying flux as high as 3.0 kg/(m2•h) for separation of 90 wt% EtOH aqueous solution at 75 °C.
