Investigations on Wastewater Pollutants Using Derivative Spectroscopy

摘要

Using two examples (uric acid determination in municipal wastewaters and nitrate/nitrite determination in less organic polluted surface or ground waters) some advantages of derivative spectroscopy in the UV/VIS-range for the quantitative evaluation of water pollution loads are demonstrated. By careful observing and avoiding matrix effects derivative spectroscopy can be applied directly to the analysis of sample constituents with a minimum of preparation and separation expenditure compared to standard methods.
