Abstract

The invention shortens the preparation time for carrying out gold atomic-absorption analysis in a mineral raw material of different composition. A batch of the mineral raw material is treated with ammonium chloride in nitric acid or with solution of ammonium nitrate in hydrochloric acid in an amount of 1 g of ammonia salt per 10 ml of acid.

Description

(57) Изобретение сокращает время подготовки пробы для атомно-абсорбционного анализа золота, содержащегося в минеральном сырье разнообразного состава. Навеску минерального вещества обрабатывают раствором хлористого аммония в азотной кислоте или раствором нитрата аммония в соляной кислоте из расчета 1 г аммонийной соли на 10 мл кислоты.(57) The invention reduces the sample preparation time for atomic absorption analysis of gold contained in various types of mineral raw materials. A portion of the mineral substance is treated with a solution of ammonium chloride in nitric acid or a solution of ammonium nitrate in hydrochloric acid at the rate of 1 g of ammonium salt per 10 ml of acid.
