Rapid detection method for silicon content in zinc alloy

The invention relates to a method for rapidly detecting the content of silicon in zinc alloy, and belongs to the technical field of metal analysis and detection methods. According to the technical scheme, the method comprises the following steps: (1) weighing and dissolving a sample: weighing a zinc alloy sample, and adding a small amount of nitric acid to dissolve the sample to obtain a zinc alloy sample solution; (2) concentrating the test solution, namely heating and concentrating the zinc alloy sample solution to obtain a concentrated test solution; (3) dissolving silicon: adding a sodium hydroxide solution and hydrogen peroxide into the concentrated test solution, and heating to dissolve silicon which is not dissolved by acid, so as to obtain a liquid sample; (4) acidizing: acidizing the liquid sample to obtain a zinc alloy sample test solution; (5) diluting: diluting the zinc alloy sample solution with water according to the requirements of a detection method; (6) establishing a working curve; and (7) d
