Interaction of Rh(III) with Humic Acids and Components of Natural Adsorption Phases

To study the migration and accumulation of Rh(III) in natural systems, we have synthesized complexes of Rh(III) and fulvic acids (FA), which are dominant organic compounds of natural waters. The composition of rhodium hydroxofulvate complexes is determined at pH 7.0, and the stability constant of these complexes is calculated. Data are obtained on interaction of FA and Rh(III) hydroxofulvate complexes with components of naturally occurring reactive barriers (ferrihydrite, quartzite, clay shale, and natural aluminosilicate suspensions) at pH 4.0–8.0. The adsorption behavior of FA and rhodium fulvate complexes at the sorbents was determined to be analogous.
