description The invention provides a preparation method of a pervaporation membrane, which comprises the following steps: (1) adding a polymer membrane material into a first solvent for first dissolution to obtain a first solution; (2) adding a p-aminophenyl compound and g-C3N4 into a second solvent for second dissolution to obtain a second solution; (3) mixing and reacting the first solution and the second solution to obtain a polymer membrane casting solution; and (4) sequentially carrying out membrane forming treatment and desolventizing treatment on the polymer membrane casting solution to obtain the pervaporation membrane. The invention further provides the pervaporation membrane, application of the pervaporation membrane in hydrogen chloride gas refining, a refining method and refined hydrogen chloride gas. According to the preparation method, the pervaporation membrane for refining the hydrogen chloride gas can be prepared, and the pervaporation membrane can purify the hydrogen chloride gas generated in the isocya
