QUANTITATIVE ANALYZING METHOD OF BORON

摘要

PROBLEM TO BE SOLVED: To provide a quantitative analyzing method of boron determining boron contained in a solid sample precisely, simply and rapidly. SOLUTION: The quantitative determination of boron contained in the sample is determined precisely and rapidly by processes for: burning the sample in a pressure-resistant container, in which an absorbing liquid is injected, under an oxygen atmosphere having pressure higher than atmospheric pressure; recovering the absorbing liquid and removing impurities contained in the absorbing liquid; preparing a liquid to be tested for meaesurment by adding azomethine to the solution from which impurities are removed; and determining boron contained in the liquid to be tested for measurment.
