A HIGHLY SELECTIVE AND RAPID SPECTROPHOTOMETRIC METHOD FOR THE DETERMINATION OF IRON(II) WITH 4-(2-THIAZOLYLAZO)RESORCINOL

Kazumasa Ueda, Yoshikazu Yamamoto

Open publisher page 1 citations

Abstract

Abstract 4-(2-Thiazolylazo)resorcinol reacts sensitively with iron(II) to form a water-soluble brown complex, which spectrally has the selective absorption at 730 nm. The absorbance is constant at pH 8.9 to 10.3 and Beer’s law holds up to 120 μg of iron(II). Many ions can be tolerable, especially 3d type metals. This method is comparable to that of 1,10-phenanthroline.
