Description
Изобретение относитс к области лабораторного анализа и может быть использовано при определении содержани химических элементов, в частности металлов , в исследуемых пробах. Известен способ анализа гидрохимических проб 1 , в основе которого лежит анализ микрокомпонентов при соосаж дении их с сульфидом кадми . Этот метод эффективен только при исследовани х проб водных растворов солей микроэлементов. Известен также способ анализа проб горных пород 2J, основанный на извлечении из них гуматно-фульватного комплекса микроэлементе раствором пирсфосфата натри и определении в последнем содержани рудных элементов. Анализ вклю чает операцию мокрого окислени органического вещества пирофосфатной выт ж ки и колориметрическое или пол рографическое определение отдельных комплексов элементов. В пирофосфатных выт жках одновремен |Но определ етс углерод дл количествен- НОЙ характеристики органического материала и результаты выражаютс в отношении содержани микроэлемента к содержанию углерода. Способ позвол ет в составе гуматнофульватного комплекса определ ть ограниченное количество элементов. Дл получени более полных сведений о содержании различных элементов в пробах по указанному способу необходимо примен ть несколько методик дл определени того или иного коплекса элементов. Недостатком способа вл етс длительность выполнени анализов и соот ветственно производительность. Целью изобретени вл етс расширение возможностей способа и повышение его производительности. Поставленна цель достигаетс тем, что после извлечени гуматно-фульват- кого комплекса рН раствора пирофосфатной выт жки устанавливают равным 2 при уровне минерализации не более 5 г/л, соосаждают гуматно-фульватный комплексThe invention relates to the field of laboratory analysis and can be used in determining the content of chemical elements, in particular metals, in the samples under study. The known method of analysis of hydrochemical samples 1, which is based on the analysis of microcomponents during their coprecipitation with cadmium sulfide. This method is effective only when examining samples of aqueous solutions of salts of trace elements. There is also known a method for analyzing samples of rocks 2J, based on extracting the humate-fulvate complex of the trace element from them with a solution of sodium pirfosfosfat and determining the ore content in the latter. The analysis includes the operation of the wet oxidation of organic matter by pyrophosphate extraction and the colorimetric or polarographic determination of individual complexes of elements. In the pyrophosphate extracts, carbon is simultaneously determined for the quantitative characteristics of the organic material and the results are expressed in terms of the trace element content of the carbon content. The method makes it possible to determine a limited number of elements in the composition of a humate-complex. To obtain more complete information about the content of various elements in samples by this method, it is necessary to apply several techniques to determine one or another set of elements. The disadvantage of the method is the duration of the analyzes and, accordingly, the performance. The aim of the invention is to expand the capabilities of the method and increase its performance. The goal is achieved by the fact that after extracting the humate-fulvate complex, the pH of the pyrophosphate extract solution is set to 2 with a salinity level of not more than 5 g / l, the humate-fulvate complex
