영가철에 의한 중금속 이온 제거 평가

Abstract

There were no wastes of things to throw away in human life. But in order to be convenient for their life, men have been trying to invent several instruments in life. So, many people had convenient lives. Men have been living in convenient life due to the industrialization over the past several decades. But in order to get rid of contaminant in the environment, it is necessary to find the reasonable way to treat them. There are several methods of removing various pollutants such as phytoremediation, soil washing, reverse osmosis, nanofiltration, adsorption, ion-exchange. But there is no all-round method due to the property of pollutants. One of these ways is to use adsorbents that adsorb heavy metal in wastewater or groundwater. In this study, uZVI, nZVI was used to remove heavy metal from the aqueous solution that contained some anions. But according to several factors, adsorption rates of heavy metals are different. So some factors such as anion, time that affected the removal of various heavy metal were investigated. And the results of heavy metal removal were characterized by AAS, IC, XPS, XRD.
