Analysis for Iodide in Groundwater by X-Ray Fluorescence Spectrometry after Collection as Silver Iodide on Activated Charcoal

摘要

The report describes the determination of microgram quantities of iodide in water by X-ray fluorescence spectrometry. The iodide is concentrated by precipitation as silver iodide on activated charcoal. If a 60-mL sample is available, a concentration of 0.12 mg/L can be detected. Precision (2sigma) at the 1-mg/L level is +- 0.08 mg/L. (Atomindex citation 11:557600)
