Comparative Metal Extraction

The aim of the study was to make quantitative comparisons between the ClearEarth organic product and peat type sediments in a variety of aspects of metal effluent uptake.

This study followed earlier work which clearly demonstrated the capability of the material in field conditions.  Studies conducted on other natural organic matter (NOM) have shown that materials high in humates are able to adsorb metals from aqueos solution.

In this laboratory study natural and artificial radioactive isotopes of nickel, cadmium and uranium were used.  Conditions affecting the dynamics of uptake were varied and an assessment of the material’s holding capacity was subsequently made.
