METHOD VALIDATION-VERIFICATION FOR THE DETERMINATION OF NITRATES IN GROUNDWATERS AND SOILS
Summary:
This thesis took place at the Laboratory of Environmental Chemistry of the Department of Chemistry of the National and Kapodistrian University of Athens.
Through this work and the validation / verification process of the new alternative nitrate determination method it will be demonstrated that (a) it can be successfully applied with the available equipment of the Environmental Chemistry Laboratory and (b) that its application not only to samples of groundwater but also in soil extracts gives the desired and reliable results in terms of analytical performance (good repeatability and trueness).
The objectives of this Master thesis are:
1. verification / validation of the method for the determination of nitrate in groundwater samples to determine the analytical performance data (trueness and repeatability) with reference materials and real samples.
2. verification / validation of the method for the determination of nitrate ion in soil extracts so as to determine the analytical performance data (trueness and repeatability) with reference materials and real samples.
3. Comparison of the nitrate values determined from groundwater sample as well as from soil extracts to be analyzed by both the alternative method and the cadmium column reduction method to prove the suitability of the first method as the results of the two methods are expected to be similar to each other, but the analysis time and the reliability of the alternative method are better.
This will ensure that the methods developed will produce reliable and repeatable results so that they can be used seamlessly to control nitrate levels in groundwater and soils, in accordance with EU regulations.
