Spectrophotometric Determination of Cerium in Some Ore in Kurdistan Region – Iraq

Ahmed M. Abdulla, Omed I. Haidar

Abstract


A simple and Sensitive Spectrophotometric method was observed for trace measurement of Cerium (IV) in different serpentinite rocks in two different positions in Kurdistan region of Iraq.

The method is depended on absorbance measurement at (490 nm.) for the red complex (Ce - Sulphanilic acid) at pH = 4.75 reproducible results were obtained (Recovery 98 – 103) % for both ores and synthetic Samples of cerium in trace levels.

Keywords: red complex, serpentinite rocks, spectrophotometric, cerium
