Preparation method and application of magnesium silicate separation and adsorption material

The invention discloses a preparation method and application of a magnesium silicate separation and adsorption material, and relates to the technical field of preparation of silicate. The preparation method comprises the following steps: firstly, respectively dissolving magnesium sulfate and sodium silicate as raw materials in deionized water, mixing, promoting the reaction at a certain temperature and pressure by utilizing microwave hydrothermal reaction, carrying out acidification modification and ultrasonic treatment after washing and centrifuging, carrying out centrifugal drying to obtain magnesium silicate powder, putting the magnesium silicate powder into a glass chromatography tube, and compacting to prepare a magnesium silicate solid-phase extraction column; the method is used for separating and purifying compounds. The method is simple in process and high in yield, magnesium silicate obtained after acidification and ultrasonic treatment has a large specific surface area, rich pore structures, high me
