Abstract
A polymer-micelle complex is disclosed. The polymer-micelle complex includes a micelle having a negative charge. The negatively charged micelle is bound electrostatically to a polymer bearing a positive charge. The complex can be in turn electrostatically bound to a siliceous material so that the complex is immobilized on the siliceous material. In addition, a composition comprising a negatively charged micelle, a positively charged polymer, and an aqueous carrier is disclosed. The aqueous carrier can exhibit salinity. In the composition, the micelle and polymer can electrostatically interact so as to form a polymer-micelle complex (which can either be soluble in the aqueous carrier or in the form of a precipitate or coacervate), or, alternatively, the polymer and micelle can remain separate such that a complex is not formed therebetween. Also disclosed are certain products and methods pertaining to the aforesaid complex and/or composition, such as a filter, a method of treating fluids, a method of trapping organic contaminants, and a method of inhibiting seepage of organic contaminants.
