Study of the Properties of Artificial Composite Materials for Permeable Geochemical Barriers

摘要

We study the filtering and sorption parameters of laboratory-produced composite materials, such as sand–gels, sand–gels with an FeS activating additive, peat–gels, and commercial sorbents on the basis of cellulose coated with MnO_2, which can be used for production of permeable geochemical barriers. The carry over and the efficiency of consumption of the active component are estimated for materials with activating additives. It is shown that all the materials under study can be used as fillers for a permeable geochemical bar-rier, but each of them has its own limitations.
