Soil organic matter can be classified according to different criteria, including solubility in water, status and susceptibility to biodegradation, among others. In general, the transport of inorganic and organic substances in water and soil can be strongly influenced by the mobility of dissolved natural organic matter (DOM) and the contents of humified organic matter (HOM). On the other hand, liquid membrane systems (LM) are complex structures formed by a liquid phase that can be used to produce a partition of different substances depending on the diffusion properties and differents conditions. In this work, liquid membrane systems were used to study the effect of humic acids (HA), fulvic acid (FA) and DOM on the transport of ions (major and minor elements such as (Cu 2+ , Mg 2+ , Ca 2+ and K + among other) and low molecular weight molecules like naphthalene acetic acid (NAA). Observing that it is possible the transport of ions mainly due to complexation reactions with HS and DOM, which in turn form bridges that allow the interaction of HS and DOM with organic anions such as NAA.
