Preconcentration for Improved Long-term Monitoring of Contaminants in Groundwater
Abstract
Materials for the concentration of nitroenergetic and perchlorate targets from groundwater were developed for monitoring applications. Novel molecular imprinting and structure direction techniques were used to obtain the necessary materials. The potential for concentration of targets from ground and surface waters as well as from soil extracts was demonstrated. The functional characteristics of the materials were evaluated in order to determine the constraints on there use in inline preconcentration of targets ahead of IMS and electrochemical sensing techniques. The systems were subsequently developed at the bench level and function was evaluated using commercially available portable sensors. An initial portable prototype was also developed and evaluated under a field scenario.
