  An electrochemical method for quantitative analysis using a carbon fiber microelectrode was fully validated and applied to monitor the spatial and temporal trends of FNT residues in water resources in the Sahel. The method was validated according to the ISO/IEC 17025 requirements and EURACHEM/CITAC guidelines, which involve assessing performance parameters such as ruggedness, selectivity, matrix effects, calibration function, precision, accuracy, Limits of Detection (LOD) and Quantification (LOQ) and uncertainty measurement. Critical parameters, such as pH, pulse amplitude, frequency and step increments, were optimized. The calibration function, evaluated using linear regression, showed that the cathodic current varied linearly with the concentration of FNT in the range of 10?200 µg/L, with a correlation coefficient of R² = 0.9997. The precision of the method was confirmed using within-d.. Read More»
