Abstract
The performance of a new ultra stable, regenerable adsorbent SH-ePMO for the removal of mercury from aqueous solutions was compared with that of a commercial ion exchange resin TP-214. The operating variables studied were initial mercury concentration and contact time. The adsorption isotherms showed favourable adsorption. The adsorption isotherms were analyzed using Langmuir and Freundlich models. The Langmuir model yielded the best fit for the SH-ePMO, whereas the Freundlich model fitted best the adsorption on TP-214. The maximum adsorption capacities were 66, resp. 456 mg/g for SH-ePMO, resp. TP-214. TP-214 is capable of purifying water to ppt-levels. The adsorption kinetics showed a fast adsorption for both adsorbents. The kinetics were analyzed using Lagergren’s pseudo-first-order and pseudo-second-order kinetic models. The pseudo-first-order kinetic model showed a good agreement of the experimental data of both adsorbents. This study clearly shows the potential of the ultra stable, regenerable SH-ePMO for removing mercury from aqueous solutions and confirms the performance of the ion exchanger resin TP-214.
