| Abstract |
| In this study, a novel type of composite-adsorbent was prepared through the zeolitization process by mixing coal waste, blast furnace slag and bottom ash to remove ethanolamine(ETA) in water effectively. Mixing ratio of composite-adsorbent with optimal ion exchange and adsorption capacity was derived using mixture analysis. The removal rate of ETA can be increased by MgO and P2O5 components of blast furnace slag and carbon, inorganic component and porous of bottom ash when blast furnace slag and bottom ash are used together with coal waste, and as a result, synergy effect can be obtained. The optimum composite-adsorbent mixing ratio obtained by the response optimization was 65.56wt% for coal waste, 25.25wt% for blast furnace slag and 9.19wt% for bottom ash in the 100wt% of composite-adsorbent. Therefore, mixture analysis regression model in this study can be used for evaluating the optimum mixing ration of composite-adsorbent. |
