Abstract

A rapid and high sensitive analytical method for the trace amounts of boron in high-purity steel and silicon material has been investigated. Steel sample was dissolved in HCl-HNO3, mixture, and boron nitride in the sample was decomposed completely by treatment of H2SO4- H3PO4 fuming at 290degrees C For over 30 min. After masking of Fe by the addition of CyDTA, the pH value of the sample solution was adjusted at 8 by aqueous ammonia. The sample solution was passed through the column of anion exchange resin (Amberlite((R)) IRA-743), and B was adsorbed selectively as boric acid on the resin. After washing the column for the removal of Fe and H2SO4-H3PO4, B was eluted by small amount of 2M HCl, and was determined by ICP-MS. The limit of detection ( estimated by the 3 sigma of blank values) was 0.016 mu g/g for steel, and 0.006 mu g/g for silicon material.
