Method for detecting content of aluminum oxide in aluminum-manganese-calcium alloy

The invention discloses a method for detecting the content of aluminum oxide in an aluminum-manganese-calcium alloy, and mainly solves the technical problem that the content of aluminum oxide in the existing aluminum-manganese-calcium alloy cannot be accurately and quickly detected. According to the technical scheme, the method for detecting the content of aluminum oxide in the aluminum-manganese-calcium alloy comprises the following steps: 1) preparing a sample, removing an oxide layer on the surface of the sample, and storing the sample in a reagent bottle containing an organic solvent; (2) extracting aluminum oxide in the sample: firstly extracting aluminum oxide in the sample by using an electrolytic method, and putting the sample into an electrolytic cell for electrolysis by taking the sample as an anode, a platinum electrode as a cathode and a saturated calomel electrode as a reference electrode; (3) detecting aluminum oxide in a sample, putting the filter membrane and a filtered substance in the step (
