Предлагаемое изобретение относится к аналитической химии (непрерывный проточный анализ). Изобретение предназначено для автоматизированного определения содержания алюминия(III) и марганца(II) в растворах, таких, как почвенные вытяжки, воды различного происхождения. Предложенный способ состоит в том, что пробу вводят в поток аскорбиновой кислоты, смешивают его с потоком ксиленолового оранжевого, фотометрически определяют суммарное содержание алюминия (III) и марганца (II). После этого детектирования вводят поток двунатриевой соли этилендиаминтетрауксусной кислоты и детектируют алюминий (III) в этом потоке. Отличие предложенного способа состоит в том, что содержание алюминия (III) и марганца (II) детектируют в потоке после введения в него аскорбиновой кислоты и ксиленолового оранжевого, после чего в поток вводят динатриевую соль этилендиаминтетрауксусной кислоты и детектрируют алюминий (III) в этом потоке. Таким образом, предложенный способ позволяет проводить одновременное определение марганца (II) и алюминия (III) из одной пробы без разделения и характеризуется хорошей воспроизводимостью, селективностью и высокой производительностью. Предложенный способ расширяет возможности скоростного проточного анализатора RFA-300(Alpkem, США), предназначенного для однокомпонентных определений.The present invention relates to analytical chemistry (continuous flow analysis). The invention is intended for the automated determination of the content of aluminum (III) and manganese (II) in solutions, such as soil extracts, waters of different origin. The proposed method consists in introducing the sample into the ascorbic acid stream, mixing it with the xylenol orange stream, and determining the total content of aluminum (III) and manganese (II) photometrically. After this detection, a stream of ethylenediaminetetraacetic acid disodium is introduced and aluminum (III) is detected in this stream. The difference of the proposed method is that the aluminum (III) and manganese (II) content is detected in the stream after ascorbic acid and xylenol orange is introduced into it, after which ethylenediaminetetraacetic acid disodium salt is introduced into the stream and aluminum (III) is detected in this stream. Thus, the proposed method allows simultaneous determination of manganese (II) and aluminum (III) from a single sample without separation and is characterized by good reproducibility, selectivity and high productivity. The proposed method extends the capabilities of the high-speed flow analyzer RFA-300 (Alpkem, USA), intended for one-component definitions.
