Nano-zero-valent iron copper-loaded bimetallic molecular sieve, preparation method thereof and application of bimetallic molecular sieve in phosphorus removal

The invention provides a nano-zero-valent iron copper-loaded bimetallic molecular sieve, a preparation method thereof and application of the bimetallic molecular sieve in phosphorus removal. The preparation method comprises the following steps: mixing iron salt, copper salt, polyvinylpyrrolidone and a molecular sieve, so as to obtain a solution A; introducing nitrogen into the solution A under a stirring condition, so as to further remove air; and dropwise adding a sodium borohydride solution into the solution A under the stirring condition and the protection of nitrogen, and carrying out centrifugation, washing precipitates, and drying, so as to obtain the nano-zero-valent iron copper-loaded bimetallic molecular sieve. Compared with the prior art, the sieve has the advantages that the particle size of nano-iron copper prepared by virtue of the preparation method is about 50nm, and the nano-iron copper is highly dispersed to the surface of a molecular sieve, so that the surface energyand the reaction activity
