“…32 The obtained limit of detection (LOD ¼ 2 ng mL À1 ) is signicantly lower than that obtained using the same BODI-PYTD chemosensor, but applying univariate calibration (LOD ¼ 5.5 ng mL À1 , ref. 18), and this is a clear demonstration of the positive effect of the multivariate calibration on the sensitivity of the analysis. 23 The relative error of prediction (REP ¼ 3%) indicates a very good precision.…”

“…Although the United States Environmental Protection Agency (US EPA) 36 has set a maximum contaminant level of Hg(II) in drinking water at 2 ng mL À1 , and a tolerance limit in surface water of 10 ng mL À1 , 37 higher concentrations can be detected (>50 ng mL À1 ) in industrial wastewaters. 18,38 As a conclusion, the LOD calculated applying the present methodology is appropriate for determining Hg(II) ions in environmental samples (surface waters and industrial wastewaters), as suggested by the US EPA, with the advantage that it was obtained by applying a simple method with a minimal sample treatment, and without using organic solvents. The above described EJCR test was applied to these samples (data not shown) and the obtained result, with the theoretically expected values of slope ¼ 1 and intercept ¼ 0 included within the corresponding ellipse, corroborates the accuracy of the method.…”
