Utilización de resinas catiónicas en el estudio de sustancias húmicas

Abstract

[ES] En este trabajo se estudia la acción de dos extractantes (resinas catiónicas y solución 0,5N de NaOH) sobre la estructura de las fracciones húmicas. Se observa, por análisis de grupos funcionales y espectroscopía infrarroja, que los ácidos húmicos extractados con resina tienen mayor contenido en grupo oxhidrilo, carbonilo y quinona, mientras que los fúlvicos extraídos con NaOH presentan mayor cantidad de grupos ácidos.

[EN] In this work we study the action of two extractors -cationic resins and solution NaOH 0,5N- on the composition of the humic fractions. We have observed, by analysing the functional groups and by infrared spectroscopy, the humic acids extracted by resin have a higher content of hydroxyl, carbonyl and quinone groups, while the fulvic acids extracted by NaOH have a larger quantity of acid groups.
