Abstract

A rapid and precise method for SIMULTANEOUS measurement of ferrous and ferric ion concentrations in solution with new synthesized b diketone (2 METHOXY BENZENE THIOL ACETYL ACETONE) is reported. The determination of both ferric and total iron concentration is maded in the same solution at the same light wavelengths, which significantly reduces the error of the analytical procedure. The method is based on the colorimetric measurement of red colored ferric-b diketone complex formed at low pH. After the addition of Hydrogen peroxide which leads to the oxidation of ferrous ion, the b diketone (2 METHOXY BENZENE THIOL ACETYL ACETONE) forms a complex with all the iron ions in solution. The maximum wavelength of the complex was 464 nm. The relationship between iron concentration and the absorbance obeys beer's law under the optimum conditions that were studied. The optimal ratio and volumes of the reagent used were also determined. The effects of the interference ions were studied. It was found that the color complex was stable for a long time (at least 10 h).
