Development of HUMASORB{trademark}, a lignite derived humic acid for removal of metals and organic contaminants from groundwater
Heavy metal and organic contamination of surface and groundwater is a major environmental concern. The contamination is primarily due to improperly disposed industrial wastes. Decontamination of surface and groundwater can be achieved using a broad spectrum of treatment options such as precipitation, ion-exchange, microbial digestion, membrane separation, activated carbon adsorption, etc. The state-of-the-art technologies for treatment of contaminated water, however, can in one pass remediate only one class of contaminants, i.e., either VOCs (activated carbon) or heavy metals( ion-exchange). The groundwater contamination at different Department of Energy (DOE) sites (e.g. Hanford) is due to the presence of both VOCs and heavy metals. Therefore, two different stepwise processes are needed to remediate a site. The two-step approach increases the cost of remediation. A novel material having properties to remove both classes of contaminants in one step is being developed as part of this project. The objective of this project is to develop a lignite derived adsorbent, HUMASORB{sup TM}, to remove heavy metal and organic contaminants from groundwater and surface water streams in one processing step. As part of this project, HUMASORB{sup TM} is being characterized and evaluated for its ion-exchange and adsorption capabilities.
