Feasibility of iodine determination in pellets with Laser-Induced Breakdown Spectroscopy
Popis výsledku v původním jazyce
The work is based on iodine detection in pressed pellets using LIBS. Generally, detection of halogens using such method has been regarded challenging1. For this study a double pulse (DP)-LIBS system was employed. It consists of a Nd: YAG 266 nm ablationlaser and a Nd: YAG 1064 nm re-excitation laser, both arranged in orthogonal configuration. The mail goal was to compare different types of binders, non-conductive and conductive ones. From the first category, frequently used microcellulose and from thesecond one silver powder was used. We focused on the influence of the binder on sensitivity and changes in set of accessible lines of iodine. The observed iodine atomic and ionic lines fall to interval of 500-600 nm. Iodine emission was measured at LIBSof potassium iodide and potassium iodite salts mixed and pressed with a binder. The iodine content was in the range of several percents. Secondly we studied effect of nanoparticles on emission intensity enhancement.
