Analysis and environmental fate of EDTA and ETPA
In this thesis, analytical techniques for the determination of two metal complexing agents, EDTA and DTPA, in aquatic environments were investigated with the main emphasis on the pulp and paper mill waste waters and the receiving natural waters. These compounds are widely used as metal chelating agents in industry. The behavior of EDTA and DTPA in waste waters and in the natural aquatic environment was investigated. In addition, the impact of EDTA and DTPA on heavy metal toxicity was studied. The thesis consists of a literature survey deals with the analytical methods developed for the determination of these aminopolycarboxylic acids. The review consists of a critical comparison of the advantages and disadvantages of chromatographic, electrochemical, spectrophotometric, titrimetric and atomic absorption methods for their applicability to the determination of EDTA and DTPA in waste and natural waters.
