    • A composition and an assay solution for the determination of dissolved iron concentration comprising an α-diimine compound and a reducing agent are described. The α-diimine compound acts as a colorimetric iron sensor. The α-diimine compound coordinates to ferrous ions in solution to give a colored diimine-iron complex. The absorbance of the resulting diimine-iron solution is measured and is a function of the analyte's iron concentration. The iron concentration of a solution can be determined by treating the solution with the present composition, measuring the absorbance, and comparing the absorbance to the absorbance of assay standards of known concentration.
    • 描述了用于测定包含α-二亚胺化合物和还原剂的溶解铁浓度的组合物和测定溶液。 α-二亚胺化合物作为比色铁传感器。 α-二亚胺化合物与溶液中的亚铁离子配位,得到着色的二亚胺 - 铁络合物。 测量所得二亚胺 - 铁溶液的吸光度,并且是分析物的铁浓度的函数。 可以通过用本发明组合物处理溶液,测量吸光度,并将吸光度与已知浓度的测定标准品的吸光度进行比较来确定溶液的铁浓度。
