METHOD OF PREPARING HIGH-PURITY ALUMINIUM FOR ANALYSIS FOR MICROIMPURITIES

摘要

Usage: for the preparation of high-purity aluminum sample therein when determining trace. SUMMARY OF THE INVENTION: From the initial sample of high purity alumina chlorination concentrated impurities of the sample with carbon tetrachloride with concurrent distillation of bases in two-piece glass vial placed in a vertical tube furnace, at different temperature gradients ampoules sections. The temperature of ampoule section in which the chlorination is maintained at 230-250 & amp; deg; C. The lower section after separation becoming t again in an oven for 5-6 minutes to remove excess carbon tetrachloride and dissolved therein aluminum chloride. The residue admixtures used in atomic emission analysis method 1 ZP f-ly, 1 pr.
