The invention relates to a mixed matrix type cation exchange membrane and a preparation method thereof. The cation exchange membrane takes a sulfonated modified polymer material as a substrate and isdoped with Schiff base type covalent organic framework materials loaded with different functional groups.

The invention relates to a method for removing a trace amount of toxic pollutants in water by enzyme-loading magnetic particle reinforced flocculation. The method comprises the following steps that 1, enzyme-loading magnetic particles are used, an enzymatic cross-coupling polymerization reaction is controlled so that a trace amount of toxic pollutants enter into an organic macro-molecule structure by covalent binding, and after the reaction, the hydrophobicity and molecular weight of the organic structure are improved; 2, the enzyme-loading magnetic particles are subjected to magnetic recovery; and 3, the recovered enzyme-loading magnetic particles are added with a flocculating agent, and the pollutants obtained by enzymatic polymerization are easily precipitated and removed by coacervation/flocculation processes such as double electrode layer compression, adsorption electrical neutralization and precipitation net-capturing and thus a trace amount of the toxic pollutants in water are removed by enzyme-loading magnetic particle reinforced flocculation. The method has good selectivity and good treatment effects on low-concentration toxic pollutants, realizes recovery and use of an enzyme, has a low cost and a wide application range and is suitable for treatment on natural water, drinking water and waste water containing low-concentration toxic pollutants.

A hydrophilic coating can be optionally corrosion resistant and/or microbial resistant for a substrate such as a heat exchanger. The coating is provided by a zeolite layer that can be formed from a synthesis solution comprising a structure directing agent, a base, a silicon source, an aluminum source, and a solvent. In one preferred embodiment, the synthesis solution comprises tetrapropylammonium hydroxide, sodium hydroxide, aluminum oxide, tetraethylorthosilicate, and water. The layer is characterized by a zeolite MFI structure and by a composition having the formula of M_n/m[Al_nSi_(96-n)O₁₉₂], or [Al_nSi_(96-n)O₁₉₂].4[(CH₃CH₂CH₂)₄N—OH] wherein M is a metal ion of valence m⁺ (e.g., Na⁺) and 27>n>=0. After formation of the coating, the organic structure directing agent can be left intact inside the zeolite coating to make the coating corrosion resistant. Alternatively, and after removal of the organic structure directing agent, a biocidal metal ion can be incorporated into the coating by an ion exchange process to render the coating microbial resistant. A hydrophilic coating that is also corrosion resistant and microbial resistant can be made by a zeolite coating with two sub-layers—the bottom sub-layer being corrosion resistant and the top sub-layer being microbial resistant.
