摘要： Membranes for fluid separation are disclosed. These membranes have a matrix layer sandwiched between an active layer and a porous support layer. The matrix layer includes 1-D nanoparticles that are vertically aligned in a porous polymer matrix, and which substantially extend through the matrix layer. The active layer provides species-specific transport, while the support layer provides mechanical support. A matrix layer of this type has favorable surface morphology for forming the active layer. Furthermore, the pores that form in the matrix layer tend to be smaller and more evenly distributed as a result of the presence of aligned 1-D nanoparticles. Improved performance of separation membranes of this type is attributed to these effects.

摘要： A method for reducing a boron concentration in a boron-containing aqueous liquid involves administering micelle(s) for selective boron adsorption to the boron-containing aqueous liquid to produce boron-bonded micelle(s), wherein the micelle(s) comprise a reaction product of an N-substituted-glucamine and a glycidyl ether; passing the micelle-containing aqueous liquid through a membrane to separate the boron-bonded micelle(s) from the aqueous liquid; and recovering a permeate having a reduced boron concentration from the membrane. A material capable of selectively adsorbing boron from a boron-containing aqueous liquid contains at least one micelle having a hydrophobic tail and a head comprising a hydrophilic functional group having formula (I): R1—O-A  (I) R1 represents a hydrocarbon group selected from the group consisting of substituted and unsubstituted aromatic, linear aliphatic, and branched aliphatic hydrocarbon groups and mixtures thereof, and A contains hydroxyl and amine groups.
