Surface modification of Zero Valent Iron Material for Enhanced Reactivity for Degrading Chlorinated Contaminants in Water

Environmental remediation in areas contaminated with pollutants typically employ iron-based treatment when cleaning pesticides and heavy metals. In this process the addition of a second metal enhances the reactivity of lead. This is because the metal serves as a catalyst, thus reduction can happen much quicker. The issue is that these metals themselves...

A device and technique to allow high resolution delineation of contaminant concentrations, biogeochemical processes, and microbial communities in saturated subsurface environments

Over the years, numerous technologies and prediction models have been developed to both predict where and how fast the subsurface contamination will move and how it might affect groundwater. However, all of these technologies are contingent on understanding the location of the contaminants, how much contamination is present, and what processes are affecting...

Rapid Analysis of Metal-laden Water via Portable X-ray Fluorescence Spectrometry.

Water salinity is vital to environmental quality assurance, environmental health, and human health. Soil and water salinity are naturally linked on slurries or saturated pastes whereby salts precipitated in soil dissolve into solution. Currently, this type of salinity analysis is conducted by using electrical conductance. Salts in soil and water are...

Synthesis of portable x-ray fluorescence spectrometry and visible near infrared diffuse reflectance spectroscopy for soil chemical characterization

Traditionally, time-consuming lab-centered routines that are based on raster sampling and wet chemical analysis are utilized for a comprehensive physicochemical soil analysis. However, these methods are time consuming and highly expensive and, thus, not practical nor convenient for the mapping of soil properties over large areas. The disclosed technology...
