Influence of naturally occurring organic and inorganic coatings on surface properties of mineral phases in recent marine sediments (Adriatic sea)
The influence of naturally occurring organic and inorganic compounds existing on the surfaces of mineral particles in marine sediments was investigated with respect to their surface physico-chemical and electrochemical properties. Bulk sediment and the clay fraction were investigated before and after removal of organic matter and Fe and Mn oxides/oxyhydroxides. It was found that organic matter induced aggregation of particles into larger organo-mineral aggregates and lowered their specific surface area (SSA) and cation exchange capacity (CEC). The role of organic coatings in the formation of surface charge of mineral particles was established. The influence of Fe and Mn oxides/oxyhydroxides on the surface reactivity of mineral particles was not consistent. Their presence increased SSA and reduced CEC of mineral particles.
