[ES] Se ha estudiado el fraccionamiento de las diversas formas de hierro y manganeso por dos métodos químicos; extracción por HCl en gradiente de concentración y extracciones sucesivas con un mismo extractante (HCl 4N), sobre un grupo de materiales sintéticos procedentes de envejecimiento en diversas condiciones de hidróxido de hierro o hidróxidos de hierro y manganeso, perfectamente caracterizados y sobre algunos horizontes de suelos típicos. Los resultados indican una buena concordancia entre los dos métodos para los productos sintéticos y suelos cuando ambos métodos separan dos o a lo sumo tres componentes distintos por material y una correspondencia menos estrecha cuando los materiales son más complejos. Se discuten las razones de la falta de paralelismo entre ambos métodos y las ventajes de cada uno.
[EN] The fractionation of different iron and manganese forms has been studied by two chemical methods: extraction by a gradient of concentration with HCl and successive extractions with the same extractor (HCl 4N) on a group of synthetic materials from aging in different conditions of iron hydroxide or iron and manganese hydroxide, and on horizons of some soil types. The result show a good correlation between the two methods for the synthetic products and soils, when both methods separate two or at the most three different components per material. However, the results show a poorer correlation when the materials are more complex. The reasons for the lack of parallelism between both methods and the advantages of each one are discussed.
