Determination of Extractable Organically Bound Fluorine in Surface Water

This technical report presents a method for determining extractable organically bound fluorine (EOF) in surface water using molecular absorption spectrometry (MAS). The method addresses the growing environmental concern regarding fluorinated organic compounds, which are increasingly found in various products and applications. The report outlines the procedure involving solid phase extraction (SPE) combined with MAS, detailing the materials, methods, and instrumentation used. It describes the sample preparation process, including the conditioning and elution of samples, and provides specifications for the equipment utilized. The results section includes measurement data from river water samples, demonstrating the effectiveness of the method in quantifying EOF concentrations. The report also discusses recovery rates for different fluorinated organic substances and the influence of inorganic fluorine on the measurement process. Overall, the findings indicate that the proposed method is suitable for rapid monitoring of environmental pollution by fluorinated compounds.
