Scientific Essentials of Developing Geochemical Sorption Barriers against Lead Based on Aminoplastic-Ground Composite Materials

摘要

A procedure was developed to obtain a lead-protective sorption barrier based of sandy grounds modified with an uncatalyzed aminoplastic oligomer. The optimum component proportions in the ground composite were found in experiments. It was shown that the sorptive capacity of modified sandy ground considerably exceeded that of montmorillonite. The composite of this formulation is capable of adsorbing up to 500 mg of lead per 1 cm~3 with loose packing with no compacting.
