Method for simultaneously and rapidly measuring contents of multiple elements in ferrous magnetic material

The invention discloses a method for simultaneously and rapidly determining the contents of multiple elements in a ferrous magnetic material. The method comprises the following steps: firstly, dissolving a to-be-detected sample in a solution; then preparing the single-element standard solution into 3-5 parts of standard solution with gradient concentration, and dissolving each part of standard solution in the solution; then carrying out data acquisition on the emission spectrum light intensity of the iron, cobalt, nickel, zinc and silicon elements of the ferrous magnetic material standard solution, drawing a standard working curve of each element according to the corresponding relationship between the element content and the emission spectrum light intensity, and substituting the emission spectrum light intensity of the iron, cobalt, nickel, zinc and silicon elements of the sample to be detected, which is acquired by the instrument, into the standard working curve; and calculating the contents of iron, cobalt
