| Abstract: | A useful method is proposed for the determination of trace amounts of iodine in geological samples by molecular absorption spectrometry of thallium iodide with platform graphite furnace.Pyrolysis has been established as an effective method using mixture flux(vanadium pentaxide and carbon powder) to be used for release of iodine in geological samples.Test were carried out to optimize the pyrolysis temperature,sample/mixture flux ratio and collecting solution volume.Determination results of the standard samples with thier recommended value are agreement. |
