Abstract:

A fixed mass of activated carbon as adsorbent was tested for the removal of organic pollutants (phenol, butanol, butan-2-ol and 2- methyl butan-2-ol) from an aqueous solution via batch adsorption experiment. The effect of the pollutants initial concentrations and contacting (agitation) time on pollutants adsorption was investigated. The purpose of the research is to determine the rate of adsorption (adsorption kinetics) of a quaternary system comprising of phenol, butanol, butan-2-ol and 2-methyl butan-2-ol, using activated carbon as the adsorbent. This will achieve the objective of assessing the adsorbent capacity in removing the organics as a function of time from the liquid phase. The adsorption kinetic of the process was carried out through experimentation and analysis which follows first order kinetic model. The results of the batch experiments adsorption kinetics showed that activated carbon exhibited high sorption capacities toward the organic pollutants and were presented in break through curves. The curves indicated that all the organic components experience high adsorption kinetics within the first 30 minutes, with phenol taken the lead. Phenol and butan-2-ol had reached their peak of adsorption at 120 minutes, and at 150 minutes, they were completely removed from the solution. From the analysis, it was concluded that adsorption using activated carbon as adsorbent favours phenol and butan-2-ol more than the other two organic components. To improve on the design of a multi-component adsorbent reactor and to find the best operating conditions, the fundamental equilibrium and kinetic data for adsorption processes are essential.
