Abstract
In this paper, we present our initial attempts to determine concentrations of nitrates, nitrites, and phosphates using spectroscopic methods as an alternative to currently employed laboratory techniques. The developed measurement techniques, based on photonic technologies, will be applicable in monitoring systems for assessing the quality of water resources in rivers, lakes, and reservoirs and in monitoring the quality of wastewater in municipal and industrial treatment plants. Current monitoring methods utilize various mechanisms for detecting and measuring the concentration of hazardous substances, such as chemical reactions involving the substances under investigation or methods that permanently alter the samples subjected to analysis (flame atomic absorption spectroscopy). The spectroscopic methods will solely rely on the non-destructive interaction of electromagnetic radiation with the substances under investigation, allowing for the maximum reduction of the method's impact on the analyzed sample.
