Method for analyzing contents of chromium, nickel, vanadium and manganese in precision alloy

The invention belongs to the field of analytical chemistry, and particularly relates to a method for analyzing the content of chromium, nickel, vanadium and manganese in precision alloy. The method comprises the following steps: S1, weighing 1 part of a sample of the precision alloy containing chromium, nickel, vanadium and/or manganese, and adding aqua regia to dissolve the sample to form a solution to be detected; s2, weighing 1 part of high-purity iron with the same weight as the precise alloy sample, and adding aqua regia with the same volume fraction as that in the step S1 to form a blank solution; s3, dividing the blank solution into a plurality of parts, and adding standard solutions with different parts; s4, performing analysis by adopting an inductively coupled plasma atomic emission spectrometer to obtain standard curves of chromium, nickel, vanadium and manganese; s5, analyzing the to-be-detected solution taken out in the step S1 by adopting an inductively coupled plasma atomic emission spectromete
