During the measurements of total iron the composites composition have huge effect of the stability of tris 1,10phenanthroline iron (II) complex. The main aim of this work is to measurement of concentration at which the stability of tris1,10-phenanthroline iron (II) complex in a given time duration is highest for alumina composite. The alumina is use as a composite in different concentration. The stability studied in the time duration of 45 minutes. This study is based on primary sources. Absorbance is measured by using UV Spectrophotometric method. The alumina having concentration 3g/200cm3 and 4g/200cm3 are form stable complex and so this concentration are suitable for the analysis of iron in this composite. And the result shows increase in absorbance with the increase in concentration the composite obeys beer Lambert law. And conclusion shows that the researcher has to focus on the stereochemistry of complex formation in the different composites.
