The invention provides a collagen/polyvinyl alcohol enzyme-loaded nanofiber as well as a preparation method and application thereof, and belongs to the technical field of nano adsorption materials. The preparation method comprises the following steps: firstly, sequentially mixing a collagen solution and an enzyme solution with a polyvinyl alcohol solution to obtain a spinning solution, and then spinning the spinning solution to obtain the collagen/polyvinyl alcohol enzyme-loaded nanofiber. The enzyme is added into the spinning solution, so that the molecule enrichment capability of the fiber is improved, the formation of a fusiform structure is promoted, and the adsorption efficiency of the nanofiber is improved. The prepared nanofibers contain rich hydrogen bonds and are large in specific surface area, physical adsorption and chemical adsorption exist in the nickel ion adsorption process, the physical adsorption plays a main role, the adsorption effect is enhanced through the hydrogen bond acting force and V
