Advanced remediation in the presence of ferrous iron and carbonate-containing water by oxygen-induced oxidation of organic contaminants.

Mechanistic investigations of an environmentally friendly and easy-to-implement oxidation method in the remediation of contaminated anoxic waters, i.e. groundwater, through the sole use of oxygen for the oxygen-induced oxidation of pollutants were the focus of this work.

Atmospheric pressure photoionization - High-field asymmetric ion mobility spectrometry (APPI-FAIMS) studies for on-site monitoring of aromatic volatile organic compounds (VOCs) in groundwater.

A continuously operating system for monitoring groundwater contamination by aromatic VOCs has been developed. For this purpose, a novel gas-water separation unit was to be used in combination with APPI-FAIMS. The gas-water separation unit successfully reduced the humidity in the sample flow to ≤1.
