CATALYTIC DETERMINATOIN OF TRACE IODINE BY X RAY FLUORESCENCE SPECTROMETRY |
| |
Abstract: | A catatytic method has beed developed for determination of trace iodine.It is based on the catalyis of iodine to reaction of As(Ⅲ)oxidixed withCe(Ⅳ)in diluted sul fric acid medium.The sensitivity is 0.02μg/20ml.The linear of determination is 0~2μg/20ml. |
