Determination method for aluminum content in aluminum wire for steelmaking deoxidation

The invention discloses a method for measuring the content of aluminum in an aluminum wire for steelmaking deoxidation, which comprises the following steps of: directly dissolving a sample by using acid, and adding excessive EDTA (Ethylene Diamine Tetraacetic Acid) to completely coordinate with aluminum; in a medium with the pH value of 4.5, PAN is used as an indicator, after excessive EDTA is dripped back with a copper sulfate standard solution, sodium fluoride is added to release EDTA coordinated with aluminum, then the copper sulfate standard solution is dripped back, and the mass percentage of aluminum is calculated according to the consumption of the standard solution. The invention aims to provide a method for measuring the content of aluminum in an aluminum wire for steelmaking deoxidation, which comprises the following steps: directly dissolving a sample by using acid, titrating by using an EDTA volumetric method, and calculating by using a theoretical value to directly obtain the content of aluminum
