Environmentally Friendly Detection of Trace Iron in Real and Natural Specimens: Method Development and Application
Year: 2024
Type: article
Abstract: In this study, we have developed an easy and fast spectrophotometric procedure to analyse Iron in traces using a reagent 1-(2-thiazolylazo)-2-naphthol (TAN) in surfactant cetyltrimethylammonium bromide (CTAB) solution. Iron complexes with 1-(2-thiazolylazo)-2-naphthol to give bis[1-(2-thiazolylazo)-2-naphthol] Iron. Demonstrated spectrophotometric method has been of great significance as using the micellar system instead of toxic, expensive and time taking extraction method. This method presented an improved detecting efficacy, sensitivity and coefficient of molar absorption. The Sandel's sensitivity and molar absorption coefficient were determined to be 7.0 ngcm-2 and ε 1.59×104 L mol-1cm-1 at λmax 571.5 nm, respectively. The 1:2 ratio was observed for Fe-[TAN]2 development. Linear calibration curve was obtained within 0.25-4.0 μg mL-1. At pH 9.5, complex formation occurred and remained stable for 24 hrs. Our recommended procedure was applied successfully for the investigation of Iron from various alloy, ecological, pharmaceutical and biological specimens.
