The invention discloses an inductively coupled plasma emission spectroscopy analysis method of acid soluble aluminum and acid insoluble aluminum. The method comprises the following steps: (1) preparing a serious of aluminum standard solutions, individually introducing the standard solution into an ICP spectrometer, measuring the spectral line intensities of aluminum, and drawing the work curve of aluminum; (2) adding a steel sample into a glass beaker, dissolving the steel sample by nitric acid, hydrochloric acid, and perchloric acid in sequence to obtain a composite acid decomposition liquid; and preparing two composite acid decomposition liquids according to the abovementioned step; and (3) using one composite acid decomposition liquid for measuring acid soluble aluminum; subjecting the other composite acid decomposition liquid, which is not filtered, to a constant volume treatment, adding the composite acid decomposition liquid into an ultrasonic wave generator, adding water until the distance between the water surface and the bottom of the volumetric flask is 6 to 20 mm, adjusting the ultrasonic frequency to the resonance point, carrying out vibration to evenly disperse acid insoluble aluminum in the solution, introducing the solution into an ICP spectrometer, and measuring the content of total aluminum. By adding an ultrasonic cleaning device, the difficult total aluminum analysis becomes easy, moreover, the operation is simple, and the measurement is rapid and accurate.
