The present invention relates to novel microporous zirconium silicate compositions that are formulated to remove toxins, e.g. potassium ions, from the gastrointestinal tract at an elevated rate without causing undesirable side effects. The preferred formulations are designed avoid increase in pH of urine in patients and/or avoid potential entry of particles into the bloodstream of the patient. Also disclosed is a method for preparing high purity crystals of UZSi-9 exhibiting an enhanced level of potassium exchange capacity. These compositions are particularly useful in the therapeutic treatment of hyperkalemia.

Compositions and methods for impurity removal are provided. A method comprises obtaining a first solution comprising an amino silane compound and a halide impurity. The method comprises contacting the first solution with an anion exchange resin to obtain a second solution. The second solution comprises less of the halide impurity than the first solution.

The present invention relates to the technical field of surface modification of silica, and more particularly to silica hollow sphere with a MOF composite layer and method for preparing the same. The silica hollow sphere comprises: a hollow spherical structure made of silica, an amino-silane layer covalently grafted onto the surface of the core layer, a ZIF-8 crystal layer grown in situ with amino groups serving as nucleation sites, and thiol groups distributed on the outer surface of the MOF crystals. The purpose of the present invention is to provide silica hollow sphere with a MOF composite layer and method for preparing the same. The silica hollow sphere with the composite layer exhibits good compatibility and stability in an LCP matrix, while maintaining low dielectric loss, thereby effectively improving the performance of high-frequency FPCs.
