| Abstract | ||
| A spectrophotometric determination of chromium (III) carried out with isatin as a complexing agent in the presence of hexadecyltrimethylammonium bromide (HTAB) as a surfactant for increasing the sensitivity of the system. The complex between chromium (III) and isatin formed at pH 3.0. Beer's Law was obeyed for chromium (III) over the range 0.45 – 8.50 g L-1 with molar absorptivity 1.69x104 L. mol-1. cm-1 and Sandell's sensitivity was 4.7x10-3 g cm-2. The proposed method has been successfully applied to the determination of chromium (III) in igneous rock from Snam hill in Iraq , and no other method investigated chromium (III) in same rock in order to compare with proposed method. | ||
