Abstract

1. Способ определения золота в рудах и продуктах их переработки методом нейтронно-активационного анализа, отличающийся тем, что перед облучением пробы проводят фторирование гидродифторидом аммония анализируемой пробы с мешающими примесями при массовом соотношении гидродифторида аммония к массе анализируемой пробы, равном (2-3):1, при нагревании в течение времени, достаточного для обеспечения фторирования мешающих примесей, после чего профторированную смесь подвергают прокаливанию для перевода мешающих примесей в газовую фазу.2. Способ по п.1, отличающийся тем, что фторирование пробы осуществляют при температуре около 200°С в течение 1-2 ч.3. Способ по п.1, отличающийся тем, что прокаливание профторированной смеси осуществляют при температуре 750°С.1. A method for determining gold in ores and products of their processing by neutron activation analysis, characterized in that prior to irradiating the sample, fluorination of ammonium hydrodifluoride of the analyzed sample with interfering impurities with a mass ratio of ammonium hydrogen difluoride to the mass of the analyzed sample equal to (2-3): 1, when heated for a time sufficient to ensure fluorination of the interfering impurities, after which the profiled mixture is calcined to transfer the interfering impurities into the gas phase. 2. The method according to claim 1, characterized in that the fluorination of the sample is carried out at a temperature of about 200 ° C for 1-2 hours. The method according to claim 1, characterized in that the calcination of the profiled mixture is carried out at a temperature of 750 ° C.
